timo After trying that site I see that I can't find color that I like. There are limited range of colors I can get with this algorithm. They are always desaturated 🙁 So it seems that there is no need to add more hues.
Maybe you can add checkbox that skip some steps and makes colors more saturated as a result, I don't how much changes it requires to do so.
I tried to make a color I like but it's possible only if I set every field on that color.
But in normal way it's desaturated
Diarium with that color (I changed the color for full system) And the same image but after saturation. It seems more cheerful to me.
