We really enjoy the Bombshell Babes line of figures... all the usual kinds of Patrick Keith sculpting goodness!
Each character is very distinct, and lots of different genres are covered.
Even though this is mostly earth tones, it is still possible to get contrast by staging warm and cool colors very close together. In this case, the burnt sienna hair color plays off the green of the cloak, and even the blue woad on the face.
This is why I try not to use the term "limited palette" or anything like it, since you are not really restricted in the amount of options and choices that you have, Even muted colors can still provide contrast and interest.
