Colour mixer
Mix two colours and see what you actually get.
sRGB draws a straight line between the two colours, which for opposite hues passes through grey. OKLab bends around it and stays saturated.
Result
Mixing two colours in the obvious way, by averaging their red, green and blue, gives a result that is usually darker and greyer than either. Mixing in OKLab keeps the brightness where you expect it. Both are here, so you can see what the difference costs.
How to use it
- Enter both colours.
- Slide to set the proportion.
- Click the result to copy it.

Frequently asked questions
- Why are there two ways to mix?
- sRGB is what most code does, and averaging channel by channel dips through darker and less colourful values on the way. OKLab is built so that equal steps look equal, so the mix stays as bright as the two colours it came from.
- Is this how paint mixes?
- No. Paint mixes subtractively, which is why blue and yellow make green on paper and grey on a screen. This mixes light, which is what a screen does.
- Can I mix more than two?
- Mix two, copy the result, then mix that with the third. The order changes the answer, exactly as it would with paint.
