Thanks so much for the kind word. The Random Game Setup dialog was the last thing that went in (it was a visualisation of something I had internally). so it also shows the "Tertiary Color option, but that one does not work on 90% of the cases. So while the CMY color space should work (but untested), the tertiary colors do not work. the other problem with them is that some colors are super hard to destinguish when adding them. I got some ideas from other comments and will look into how to implement that.
Again, thanks so much for playing and commenting.
