Great new colors but changing the name slate to gray would probably be a good idea. I've never even heard the word slate before and thought for a long time what S could be standing for... Now I'm not a native speaker of english but still, I'm pretty sure "gray" is much more recognizable.

Probably ...

Red and Pink look too much like each other in my opinion... In World 2.1 I really have to watch from close distance to discover which territories are mine and which not. Please make Pink a light Pink. TY The rest of the colours look fine.
