Why mix Charcoal instead of buying it
Mixing Charcoal yourself lets you approximate an expensive or hard to find tube from pigments you already own, match Charcoal 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
Overshooting on Ultramarine Blue is the usual failure, add it in 5% steps and compare against the target between each pass.
