How to Mix Dioxazine Purple in Acrylic

A very deep, transparent violet. Devastating in tiny amounts. This guide gives you the pigment ratios that land on #3A1A4C in acrylic, using the same solver that powers the Chromilla mixer.

Honest note: this palette gets close but not exactly to #3A1A4C. Expect roughly a 84% match on acrylic. Adding one tube of Dioxazine Violet (PV23) closes most of the gap.

Why mix Dioxazine Purple instead of buying it

Mixing Dioxazine Purple yourself lets you approximate an expensive or hard to find tube from pigments you already own, match Dioxazine Purple 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.
