You can make a vivid purple by mixing magenta and cyan (or phthalo blue), or colors that lie in between these two primaries. When you look for a less vivid purple, here are some options: • Add yellow (it's the third primary, and therefore it tones your mixture down). • Use one or two colors outside the range of the two primaries. For instance: pyrrole red (contains a little yellow) with cyan. • Use black, white or gray https://www.toon-nagtegaal.com/
