How to Mix Acrylic Paint

Acrylic is the least forgiving medium to mix by eye, because the paint you judge is not the paint anyone sees. It dries fast, it dries darker, and the binder clears as it cures. Chromilla solves acrylic recipes against the dried film, so the ratio you get is aimed at the colour on the wall, not the colour on the knife.

What makes mixing in acrylic different

It dries darker, by about 10 per cent

Wet acrylic scatters light through a milky binder. Once that binder clears, value drops. Chromilla models the shift at 10 per cent of value with a small warm nudge, and scores every candidate recipe on the dried result.

Open time is minutes, not hours

You cannot correct a mix on the canvas the way you can in oil. That is why the ratio matters more here: mix a measured batch, swatch it, let it go matte, then commit.

Opacity varies wildly by range

Heavy body covers, fluid and soft body do not. The same ratio over a white ground and over a dark ground can read as two different colours, so keep a scrap of your actual substrate on the bench.

White does most of the work

Acrylic recipes lean hard on titanium white, often 60 to 85 per cent of the mix. That means the two or three coloured tubes carry all the hue, and small errors in them show up large.
