How to Mix Dioxazine Purple in Watercolor

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

Watercolour reaches #3A1A4C by dilution on white paper as much as by pigment mixing. Start with the recipe above thinned with clean water and lift until the tone reads right. 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.
