I'll check that.
FWIW, all of this color thing + theme is annoying me and I started something to sort it out. Also have eye issues and one of the reasons I use Pharo is that I can customize it for my own ways.
We need a real core palette on top of which we put logical color names for the themes.
Check the GLM Themers are not fully working with themes and have hardcoded colors and some missing subclasses (I am making Sublismish from Seb work there)... AAaaah.
