Dont know what colors would fit the best

So I just started my own Region based on Austria. This is the first stage of the grass starter, based on alpine marmots and will gain a opera theme with its evolutions. In my head I imagined some kind of white mask kind of like in the Phantom of the Opera in the design of the last stage. Plus it will go more on the feminin side. Before doing the lineart I wanted to try around a bit with its colors, but I dont know wich one fits best, please help.
