How to mix two paint colors to get a specific color

To mix two paint colors into a specific target, start with the dominant hue, add the secondary color in small increments (roughly 10–20% at a time), then adjust value with white or black. Test on paper between additions — paint shifts as it dries.

Step-by-step

  1. Identify the dominant hue

    Decide which of your two tubes is closest to the target. That tube becomes the base — usually 60–80% of the mix.

  2. Add the modifier in small steps

    Add the second color in 10–20% increments. Stir fully each time. Stop the moment the swatch reads the target hue.

  3. Adjust value, not hue

    Lighten with Titanium White (acrylic/oil) or with water (watercolour). Darken with the mix's complement before reaching for black.

  4. Test wet and dry

    Paint a swatch, let it dry, then compare to the target. Acrylics darken 10–15%, oils barely shift, watercolours lift lighter.

Sample mixing ratios

Warm orange
Cadmium Yellow 70% + Cadmium Red 30%
Soft sage green
Yellow Ochre 55% + Ultramarine Blue 25% + Titanium White 20%
Cool grey
Ultramarine Blue 40% + Burnt Sienna 35% + Titanium White 25%

Ratios are calibrated as a starting point. Pigment tinting strength varies by brand — use Chromilla's color mixing calculator to recalibrate for your specific tubes.

Frequently asked questions

How much of each color should I start with?
Start with a 4:1 ratio of base color to modifier and adjust. Pigments vary hugely in tinting strength — phthalo blue is 20× stronger than yellow ochre, so a tiny dot is plenty.
Why does my mix look muddy?
Muddy mixes usually mean three or more pigments that already contain hints of each other. Stick to two pigments plus white, or use a Chromilla recipe that picks the cleanest pair for your target.
