Art Mistakes

Colour mud check

Pick up to four colours from your palette. The tool mixes each pair equally on screen and tells you which are likely to go dull.

This is a guide, not a paint test. Screens mix light, and real pigments differ by brand and by how much you stir. Treat a warning as a reason to test on a scrap.

The check looks at two things. Hues roughly opposite on the colour wheel tend to cancel to grey. Colours that are already muted give little to work with.
