The Miniature Painter’s Guide to Mixing Paint

Why Bother Mixing Paint at All?

The obvious reason is that no paint range has every colour you will ever want. Even big ranges have gaps. The exact dusty olive for an old military uniform, the right aged bone tone, a muted leather that sits between two pots you already own — a lot of the time the colour you actually want is somewhere in the middle.

But the more useful reason is control. If you are painting a unit, warband, or army and want a consistent colour across multiple models, mixing your own batch can make life much easier. It is a lot more reliable to work from one mixed pool than to try and recreate the same tone from memory three sessions later and pretend it is close enough.

That alone makes mixing worth learning.

What Actually Happens When You Mix Paint

Paint does not behave the way people often expect. In simple terms, mixing paint usually makes the result darker and less saturated. The more colours you throw in, the more likely the mix is to lose clarity and head toward something dull. That is why things turn muddy so quickly when you keep trying to fix a mix by adding more and more to it.

A few practical rules are worth keeping in mind:

• Mixing two colours usually gives you a darker, duller result than either starting colour
• The more different paints you add, the muddier the result tends to get
• Complementary colours will usually neutralise each other into browns, greys, or muted tones

Because of that, simpler mixes are usually better. Two paints is ideal. Three is often fine. Once you start throwing four or five things into the same puddle, you are usually on borrowed time.

White and Black Are Useful, but They Are Not Neutral Tools

A lot of people automatically reach for white to lighten and black to darken. That does work, but both of them come with side effects.

White

White lightens a colour, but it also tends to desaturate it and cool it off a bit. That is why adding white to something like red often gives you a chalky pink rather than a cleaner, brighter highlight.

A lot of the time, it is better to lighten with a lighter version of the same general hue instead. Cream, ivory, pale flesh tones, buff, or even a warm yellow often give a better result than pure white, depending on what you are painting. White still has its place — final edge highlights, tiny specular dots, catchlights, gems, eyes — those are all fine uses for it. Just do not treat it like the default answer every time you want a brighter colour.

Black

Black darkens a colour, but it also tends to kill saturation and can push the hue in ways you may not want. Yellow mixed with black is a classic example — it does not just become a darker yellow, it heads into a murky greenish mess very quickly.

For shadows, darker browns, blues, purples, or even deep greens often give you a richer result than black. They darken the mix without flattening it in the same way. Black is still useful, especially with neutral mixes or when you genuinely want something pushed way down, but like white, it works better when used deliberately rather than automatically.

Ratios Matter More Than People Think

When you mix paint, colour is only half the job. The other half is consistency. Miniature paints are already fairly thick, and most need at least a little thinning before they go on well. So when you mix, you are not just aiming for the right colour — you are also aiming for a paint consistency that still behaves properly on the model.

A good general starting point for normal layering is something like 2:1 or 3:1 paint to water. Thin enough to flow properly, but not so thin that it goes transparent immediately. Glazes and washes go much thinner than that, but for regular painting that is a sensible starting area.

When you are combining two paints, start with the lighter or more dominant colour first, then add the stronger colour a little at a time. Dark or intense colours can take over a mix very quickly. It is much easier to nudge a mix darker than it is to pull it back after you overshoot. That is one of those small habits that saves a lot of wasted paint.

Mixing for Layering Is One of the Most Useful Skills You Can Learn

One of the best uses for paint mixing is building a simple shadow-to-highlight range from one base colour. Instead of relying on three separate pots that only sort of relate to each other, you start with your base tone and mix outward from it. One darker version for shadows. One lighter version for highlights. Because both are built from the same original colour, the result usually feels more coherent straight away.

For the shadow side, you can often add a small amount of a darker, cooler colour — deep blue, purple, dark brown, whatever fits the scheme. For the highlight side, you usually get a better result from a lighter, warmer colour than from pure white. Cream, buff, pale flesh, or a lighter version of the same hue often works better.

That gives you a triad that feels connected and usually reads much more naturally on the model.

Skin Tones Are a Good Example of Why Mixing Matters

Skin is one of the easiest places to see the value of mixing because straight-out-of-the-pot skin paints often need adjusting anyway. A solid midtone skin mix usually sits somewhere around a warm pink or orange base, softened with something like ochre, buff, or a muted brown. The exact mix changes depending on what kind of skin tone you are aiming for, but the principle stays the same — you are balancing warmth, lightness, and some degree of desaturation so it looks believable rather than cartoonish.

From there, the shadows usually move cooler or redder, and the highlights move lighter and slightly warmer. The same logic applies to non-human skin too — orcs, undead, alien skin. The base hue changes, but the structure is similar.

Metallics Need a Slightly Different Approach

Metallic paints are their own thing because the metal flakes change how the paint behaves and how the light hits it. Mixing two metallics together usually works fine — silver into gold, bronze into steel. You still get a metallic result, just a different one.

Mixing metallics with regular paint is where you need to be more aware of what you are doing. It can work, but it tends to reduce the metallic effect. If you want to darken a metallic without completely killing the sheen, it is often better to use a wash, an ink, or a transparent darker colour rather than just dumping a normal dark paint into it. If you want to tint a metallic warmer or cooler, a very small amount of regular colour can work well. A touch of red can warm silver toward a rose-metal feel. A touch of blue can cool it down. The key is to keep those additions small.

Write Your Mixes Down

This part is boring, but it matters. One of the most annoying things in miniature painting is making a great colour, using it once, then having no idea how you got there when you need it again two weeks later. People always think they will remember. They usually do not.

You do not need a laboratory system for this. Just keep it simple:

• Keep some white card or paper near your painting area
• Put a little sample of the mix on it
• Note the rough recipe beside it
• Use actual paint names, not vague memory labels

You do not need exact measurements down to the drop. “Two parts this, one part that, tiny touch of this” is usually enough to get you back into the same range later.

Common Mistakes When Mixing Paint

Adding too many colours

This is the big one. If a mix is not working, the answer is often to simplify it, not keep feeding more colours into it. The more things you add, the more likely you are to lose clarity.

Mixing on a dry palette

Miniature paint dries fast. If you are trying to adjust a mix on a dry palette, you are fighting the clock the whole time. A wet palette gives you much more room to work and makes gradual adjustments much less annoying.

Not fully mixing the paint

If the mix still has streaks in it, it is not mixed properly. A half-mixed puddle can give you inconsistent results across the model and make you think the colour itself is the problem.

Correcting in the wrong direction

Sometimes a mix is not just too dark or too light — it is too cool, too warm, too dull, or too saturated at the same time. If you only correct one part of the problem, you can make the rest worse. For example, if a mix is too dark and too cool, adding white alone makes it lighter but even cooler. What it may actually need is something lighter and warmer at the same time. This is the part that gets easier with practice.

Final Thoughts

Mixing paint is mostly about mileage. You can read about it, and that helps, but a lot of it only really clicks once you have made enough good and bad mixes to start recognising what colours are likely to do before they touch each other.

Once you get there, you stop relying so much on owning the perfect pot for every situation. You get more flexible, more consistent, and usually a lot less frustrated. That is when mixing starts to feel less like a chore and more like one of the most useful tools you have.
