I'm looking to mix up a batch of purple solder mask. Has anyone found a good ratio of red and blue that produces a pleasing purple? 50/50 produces a pretty ugly grape color. Is there a standard ratio most fabs use?

According to the Trichromatism.Half red and half blue will get purple.But the trichromatism only apply to color light. The red and blue soder mask are coloring material.Both of them absorb light.You mixed them up,so you lose blue and red,and get grap
