Why mix Dark Brown instead of buying it

Mixing Dark Brown yourself lets you approximate an expensive or hard to find tube from pigments you already own, match Dark Brown across paint brands whose factory tubes differ, and rebuild the exact colour when you run out mid painting. The recipe above is the working starting point.

Common mistakes

Reaching for more black to deepen it kills the chroma, add the dark modifier already in the recipe instead.
