Why mix Raw Sienna instead of buying it

Mixing Raw Sienna yourself lets you approximate an expensive or hard to find tube from pigments you already own, match Raw Sienna 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

White cools and chalks a mix as you add it, so tint in small steps and stop before it goes pastel.
