Most colours suck. I want more of them and better.

Some colors are already nearly indistinguishable (Red vs Orange Red, for example) and adding more will only make the situation worse. You just can't really make more than 10 really different colours, and Warlight already has 24.

^Agreed. The only option left is to start having textures. Which could actually be kind of cool. But potentially very very busy, so good design is crucial.

Polka dots, anyone?

This might also be a solution for the other thread about colorblind players. Texture overlays.
