Why mix Raw Umber instead of buying it

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

Common mistakes

Overshooting on Viridian Green is the usual failure, add it in 5% steps and compare against the target between each pass.
