The Science of Oil Paints with Kyle Kolbe

Do you trust your paints? Do you want your miniature masterpieces to not fade or darken with time and light exposure? To mix color reliably and paint permanently you must know your pigments contained in your paint.

I delve deep into the properties of an elite palette of pigments that will let you mix the right color and save your work from exposure to time and light in a chapter of the oil painting book. You will learn the unique strengths of each chosen oil color and how the colors interact with each other.

Find out more about paint science and how picking the right pigments leads to intelligent color mixing and beautiful work in my forthcoming book, Artist’s Oil Colors Miniature Painting Handbook.

Please enjoy this preview excerpt that covers the basics of mixing oil paint colors.

Mix Oil Colors

Learn the essential oil colors needed for a full spectrum color mixing palette. Explore unique paint and color properties that guaranteed the chosen colors’ elite status. Economically mix the exact target color from the right cool and warm biased primaries, earth colors, and neutrals, plus some bonus colors suited for fantasy painting.

Witnessing an art supply store’s aisles of paint for the first time horrifies most new artists. First, pick a media: oils. Then pick a brand: Gamblin. Choose between their marketing jargon for student (lower quality) and artist colors: Artist’s Color (not 1980). Then select a balanced palette of colors. Then see the varying price tags for colors: what’s the difference between Cerulean Blue Hue and Cerulean Blue other than $30? You hit a wall of confusion and cannot rationalize the risk of buying the wrong tube of paint for $10, $20, $30 or more dollars. Where do you go from here?

Just as you would not blindly buy a new car, television, camera, smartphone, or dishwasher uninformed, you cannot invest in oil paints without some knowledge of how they are organized and how they work. Read on to discover the colorful world of oil paints.

Buy Your First Palette of Oil Colors

Unless you have thousands of dollars, you cannot buy a whole manufacturer’s line of oil colors. You must select the best colors. You should buy the highest quality artist colors you can afford. You need enough versatility in your palette so you can arrive at any color by mixing an elite set of pure pigments, neutrals, and earth colors. Read on to gain the knowledge needed to make informed paint purchasing decisions.

More than a Tube

You may be shocked to find that not all artist paint colors are priced simply by the volume of paint like you may be used to with hobby paints. Beyond volume, pigment and vehicle quality determines the price. Manufactures separate artist quality paints into different “series” (depending on manufacturer, series 1-7 or A-G). Paint producers price the lowest series number or letter cheaper than the highest series designation, ranging from under $10 to over $30 for a 37ml tube.

In addition to series, you may also find some colors with “hue” appending their name (e.g., Cerulean Blue Hue), these colors are made from a cocktail of cheaper pigments to achieve a similar color to the purer expensive pigment, but you may find color mixes turn out dirtier and you cannot mix as high a chroma final color. Sometimes a hue paint has added opacifiers (or simply titanium white) to a transparent pigment that you may find beneficial for applications that need good coverage.

False Economies

Do not compromise on quality when first presented with artist color pricing and fall into the false economy trap of buying cheaper student colors. The student colors will dissatisfy you with their more economic pigment hue mixtures, filler, and lower quality binders and have to replace them with new artist colors. When I first jumped into oil painting, I made this mistake and I have replaced my remaining student colors with artist colors. I upgraded my colors at great expense, but the quality, purity, and reliability of artist colors prove their worth.

The Zorn Mini Palette

If you are on a tight budget, then limit the quantity not the quality of colors. You can still start out with a small but highly versatile palette of colors. The Zorn palette—named after painter Anders Zorn—contains colors that are included in the larger basic palette. The palette only features four colors: Titanium White, Yellow Ochre, Cadmium Red Light (or Medium depending on manufacturer), and Ivory Black. When you are ready you can expand the Zorn palette with the additional colors below.

The Full Biased Mixing Palette

A full mixing palette contains warm and cool biased primaries, earth colors, opaque and transparent neutrals, and some convenience colors best suited for fantasy miniatures. I list the colors here and full color profiles follow in a later section.

Understand Paint Properties

Paints are more than just liquid color. Many interactive properties define artists’ colors including: pigment type (inorganic or organic), pigments, vehicle, opacity, tinting strength, lightfastness, and gloss. You will learn to make informed paint color selections based on these properties.

Paint is Paint, Right?

The simple answer is no. If you are buying paint that is the same price across all colors, then some of those colors are grossly homogenized by incorporating a cocktail of cheap pigment and fillers in place of the proper portion of pure pigment that would drastically increase the price. If your paint manufacturer of choice is more concerned about trademarking the names of their colors, then you need to find a new paint manufacturer. Hobby paint manufacturers hide the pigment mix of their paints primarily to protect their intellectual property, but also because the list of ingredients might not fit on the bottle. The homogenized paint lines force you into buying a large selection of premixed colors, like a box of crayons because they know you will become frustrated trying to mix new colors from their crippled, multi-pigment, and who knows what else, colors.

Why Are Artist Colors Better?

Artist colors are priced according to the pigments that end up in the tube. Many inorganic pigments are natural resource commodities whose prices are set by the market, while organic pigments are priced by their cost of development and manufacture in labs. You can easily spend more than $30 on a small tube of Cadmium Red Light or Cerulean Blue because their inorganic pigments are ground from rare earth materials. Buying these expensive pigments will guarantee you more predictable color mixing and permanence. Working with artists colors also expands your color mixing gamut well beyond the limitations of hobby paints (held back by their inferior or diluted pigments and fillers).

So I can just buy any Artists Color and get great results?

Unfortunately, no. Artist color manufacturers make many superfluous paint colors for historical reasons (like Alizarin Crimson, a poor, fading red-purple used by impressionists and other old masters because they had nothing better at the time, and it is still suggested for most beginning palettes), or with convenience colors that can be easily mixed from superior pigments. While these manufacturers name artists colors more consistently than hobby manufacturers, you cannot solely invest in a color based on its name. “Yellow Ochre” from one manufacturer may use different pigments than another.

You need to be informed and selective when shopping for artist color paint. Always read the paint’s ingredients listed on the tube and any other properties the manufacturer publishes. If you cannot find documentation for the ingredients or properties listed in the color profiles, then avoid that manufacturer.

To help you make the best buying decisions, study the color profiles at the end of this chapter.

Mix Colors Smarter

Cut to the chase: Colors can be defined and identified by their hue, value, and chroma. All paint hues contain biases to a neighboring color hue, meaning that no paint can represent a pure “primary” color like red, blue, and yellow to mix all other colors. By recognizing the biases we can intelligently mix new bright, middling, or dull colors by combining the right pure pigment paint colors.

Understand Munsell Color Notation

One of the limitations you may find frustrating with hobby acrylics is the lack of high saturation color, or chroma. To understand this limitation and how you can overcome it with your investment in artist colors, you need a brief primer on color notation as devised by Munsell.

The Munsell color system categorizes colors by value (lightness from black (0), grey (1-10), and white (11)), hue (position on the spectrum moving through red, yellow-red, yellow, green-yellow, green, blue-green, blue, purple-blue, purple, and red-purple), and chroma (intensity of color saturation from grey (0) stepping in twos up to 16 or 18 (though most computer screen gamuts can only show up to 12 or 14 depending on the hue).

When you view a single hue’s mapping of chroma and value, you will find a swatch where both chroma and value max out, this is the hue’s maximum brightness. The major hues reach maximum brightness at different points on the value scale.

You will find Munsell notations on each of the color profiles. For example, Ultramarine Blue’s Munsell hue, value, chroma notation reads: 7.5PB[hue, a blue-leaning purple-blue]-2[value, very dark, remember 0 is black]-10[chroma, strong saturation].

Do you want to learn to mix any color predictably from a limited palette?

Does mixing paint terrify you? Is it rare that you get the color you need to match or had imagined? In this section, we will explore the concepts and tools needed to overcome your fear of mixing colors and enter a world of predictable color.

Your childhood art instructors lied to you about red, blue, and yellow. They oversimplified mixing primary colors. Your teachers and parents presented a simple to follow path from three primaries to three secondaries to six tertiaries. They should have started at the end with the tertiaries and instilled the concept of color bias. If they taught you about color bias, then you would have been mixing predictable colors from a young age. Now you can leave those years of frustration with muddy over-mixed palettes of wasted paint behind you.

Know Your Color’s Bias

Instead of naming primary and secondary hues simply, like: blue, red, yellow, orange, green, and violet, we can introduce their bias into the naming like Munsell intermediary hues: yellow-red, green-yellow, blue-green, purple-blue, red-purple. If we introduce the principle Munsell hues of Red, Yellow, Green, Blue, and Purple, then we can easily find color complements by name matching opposite principle and intermediary hues: red complements blue-green, yellow complements purple-blue, green complements red-purple, blue complements yellow-red, and purple complements green-yellow.

To understand color bias in paint colors, you must know your destination color, the destination color’s hue complement, and the absence or presence of that complement color in your mixing colors. When the destination color’s hue complement is present in one or both of the mixing colors, the resulting chroma will be minimized (gray, dull, dim, lifeless). When the complement is absent from both of the mixing colors, you will maximize the resulting chroma (colorful, saturated, bright, vibrant). The following examples will make this clear.

Pick a bright (nexus of maximum chroma and lightest value) purple. We know that red and blue mix to purple, but we don’t have a pure red or blue (because they don’t exist), so what paint tubes do we reach for? Well, we know our destination hue of purple but now we need to know its complement, green-yellow, so we can avoid it in our mixing colors. The name green-yellow tells us the two colors we don’t want dirtying our mixes, we don’t want any green in our blue and yellow in our red. So now we can make a predictable bright purple from a blue biased away from green and toward purple and a red biased away from yellow and toward purple. You could make a the destination purple from ultramarine blue and magenta. If we need to dull the purple we can swap one of the mixing colors with a color that contains green or yellow, like a cyan or a cadmium red.

Now, let’s mix a bright yellow-red, or orange. Mixing yellow and red makes orange, but we know it’s not that simple. You need to know yellow-red’s complement: blue-green. So we need to pick a red with no blue, cadmium red light, and a yellow with no green bias, cadmium yellow medium. Mix these two colors for bright and opaque oranges.

Lastly, mix a bright green from yellow-green and blue-green. A bright green complement is a warm red containing orange and a little purple. When you mix hansa yellow light with cerulean blue you will get a bright green.

All color mixes can be dulled by mixing with colors that move away from a common bias. For example, if you mix quinacridone magenta and cerulean blue you will still get a purple but it will be greyed by the complements present in each pigment as they cancel out light reflectance.

Refer to the oil color profiles for lists of mixes and visual examples on the palette.

Manipulate Paint Properties

To achieve a pleasing finish in a timely manner you must condition the paint and cure the paint on the model in a controlled environment. Follow these tips to get full control of your paints and avoid nasty surprises.

Control the Cure and Reduce Shine

As a miniature painter, you work under the pressure of deadlines. You may need to finish a single miniature, a skirmish crew or an army for a client in the next week. Maybe you need to have your combat group painted for a tournament this weekend. Deadlines frighten the artist into taking shortcuts and relying on instant dry acrylics. Oils seem counter-intuitive to deadlines. If not properly handled, some colors can take days or weeks to cure (notice the absence of the term “dry,” oil colors cure through the oxidation of the color’s vehicle, usually linseed oil). Some colors come out in an oil slick like Cadmium Red Medium and need a long leaching period while others like Raw Umber exit the tube stiff and require no leaching at all. We can mitigate the threat of deadlines through some simple preparation, mediums, and baking.

Follow the tips below to take control of your curing time:

Leach: Avoid squeezing an oily blob of paint straight from the tube onto your palette. Instead, expel the colors onto a scrap of brown craft paper or paper grocery bag. A small stain of oil will radiate and absorb into the paper leaving you with a stiffer color pile resulting in a less glossy finish and reduced curing times. Most colors will properly leach in 15–20 minutes. Once most of the oil coating transfers from the paint to paper, scrape up the paint pile and transfer it to your mixing palette.

Thin: Oil colors are meant to be applied at full strength and spread thinly on the surface of the mini. The leaner we make colors with solvents (Gamsol or Odorless White Spirit) the less gloss of the fat oil remains. Solvents can be too harsh though and we can use oil mediums (a special cocktail of oils, solvents, and dryers) for better results. Unfortunately, most commercial mediums’ first feature reads “increases gloss.” How do we get a pleasing matte surface? Our options are limited to one pre-mixed medium: Grumbacher Oil Painting Medium I. This medium leaves a matte finish while improving the flow of paints. Perfect.

Bake: When all blending is finalized and you need a dry surface for the next phase of painting, place the piece in a drying box. See the recipe to build your own box in the studio set up section. The simple light bulb in a box both heats the paint layer (metal and resin figures can withstand the heat from the bulb, but test plastics against the heat) and exposes it to UV light curing most colors within 24 hours and finishing a matte surface.

Now that you know how to manipulate the curing time of your masterworks, those deadlines don’t seem so scary.

Expect Color Sinking

When I first applied a bright white edge highlight to a sword, I was disappointed the next day to find the white had gone dull and it looked like I needed another layer. This dulling change is called “color sinking.” As oil colors cure they lose some of their opacity and sink into the underlying paint color. The effect is subtle and sometimes a benefit for very subtle shifts in color modulation. You can combat sinking by applying the right value underpainting beneath the top color. You can even bump up the value a level to get brighter highlights. When you paint your final highlights you can avoid some color sinking by skipping the drying hot box and letting the paint cure longer under room temperature conditions. Color sinking can be surprising and disappointing when first experienced, but now that you understand what’s happening between paint layers, you can lessen the impact on the finished figure.

Set Up a Biased Palette

A successful painting session with oils depends on the preparation of your palette of colors. An oil palette and acrylic palette differ in a few ways. You don’t need a palette that accommodates water colors or thinned acrylics with many wells or a wet palette that keep the paint piles moist. For oils, you need a large, flat, smooth, nonabsorbent surface like a piece of glass or acrylic. I use gray palette paper secured to a clipboard as an easily disposable option. You need a flat surface so you can easily cut, pick up, and mix target colors with a palette knife. Once you obtain a suitable palette, you need to get some paint onto it.

After you’ve leached some of the oil out of each paint pile, scrape it off the craft paper and deposit it on the top and left perimeter of the palette following the same order and grouping of the color profiles (if you’re left handed set the piles along the right side). Start at the top right with a white pile, then yellows, then blues, then reds, then earths, and finally neutrals ending at the bottom left corner. The middle of the palette is reserved for your various mixes. Depending on your subject, you may not need every color on the palette but it may take some time and experience to be able to predict the base colors you will need to mix every target color accurately.

Now you need to decide if you want an open or closed palette. An open palette lets you improvise and mix colors on the fly as you need them while you paint. A closed palette forces you to premix color strings, a stepped tint and shade value range of a target hue for all of your major target colors. You may prefer a closed palette if you are used to a wide range of convenience colors with prescribed tints and shades for each color, like WarColours or Reaper MSP HD. Once you gain some experience, you may find that a partially open palette with some premixed colors leads you to the best results.

Setting up your palette consistently every session will avoid unforeseen difficulties that arise from a sloppy set up.

Know Your Color Profiles

Listed below are the main properties of paint you need to research before buying denoted with a $ along with an explanation of each color profile’s attributes:

  • Common Name: The marketing name most commonly used by paint manufacturers displayed predominantly on the tube.
  • $ Pigment: Not all pigments are created equally. All colors suggested in this book will list their pigment so you are not tricked by a manufacturer’s color name. If you venture out to new colors, then do your research using the resources listed below.
  • Pigment Family: Pure pigments fall into two families: Organic/Modern (pigments are created chemically in a lab) and Inorganic/Mineral (pigments are ground from rocks and bones).
  • Munsell Hue-Value-Chroma: The color’s Munsell notation. The values can be useful when figuring out different color schemes and successfully mixing to your intended target color.
  • $ Lightfastness: Do not compromise lightfastness. All colors on your palette should pass an ATSM I rating of excellent lightfastness. Otherwise, your poorly rated colors will fade or darken in a few years, ruining your finely crafted miniature. I see examples of this around my house everyday in framed family photos that were printed on an inkjet that used a non-lightfast yellow pigment in its ink. I watch my family slowly fade into freakish pink aliens.
  • $ Opacity: A color’s opaque, semi-transparent, or transparent property depends on the pigment. Microscopic rocks make up opaque pigments that light does not pass through, while transparent particles like shards of stained glass comprise transparent pigments. Opaque pigments can be made transparent through dilution but will not reflect back the same luminous light as a true transparent pigment.
  • $ Gloss: Pigments naturally determine a gloss or matte finish as varied as their opacity. Miniature artists prefer a matte finish to their models, and the gloss of some colors can be reduced by mixing with matte colors, matte mediums, and speeding drying time through a hot box. Finally, a matte varnish may be applied as a finishing step.
  • $ Tinting Strength: Adding white to a color tints it. Colors with a high tinting strength will retain their high chroma longer than colors with a low tinting strength when adding the same amount of white. You may have a harder time mixing with high chroma and tinting strength colors because they will dominate a mix with just a small addition of paint, while low tinting strength colors give you more room to play in your mix.
  • Why it’s in the palette: An editorial explanation of the color’s strengths and relationships with other colors in the palette.
  • Bright Mixes: A list of single color mixes where each color shares a strong bias without any contaminating complements
  • Middle Mixes: A list of single color mixes where one color is strongly biased toward the target and the other contains a contaminating complement
  • Dull Mixes: A list of single color mixes where both colors share more complements than biases
  • Complement: Within the included colors, the color’s complementary hue that mixes to a darker neutral (brown, gray, or black)
  • Undercoat Value: A suggested value of neutral undercoat to best support the color’s native value and transparency.
  • Tint: Suggested white for tinting
  • Shade: Suggested blacks and biased warm and cool colors to darken the color
