Work out paint mixing for artists instantly with clear inputs, formula shown and shareable results.
Each colour's volume is the total multiplied by its share of the total parts, so a 3:1 mix of 100 ml is 75 ml and 25 ml. Mixing by ratio rather than by eye is what lets you remix an identical batch weeks later when a painting needs touching up.
Volume per colour
volume = total x parts of that colour / total parts
volume = total x parts of that colour / total parts. Each colour's volume is the total multiplied by its share of the total parts, so a 3:1 mix of 100 ml is 75 ml and 25 ml.
Mixing by ratio rather than by eye is what lets you remix an identical batch weeks later when a painting needs touching up.
Enter parts of the first colour, parts of the second colour, total mixed volume wanted. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
