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 ...

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.
