Color tests for Illustration

I'm doing an illustration of a Jazz club/bar and here I am trying to figure out the colors for the central figure, a torch singer. I want a pin up look to the singer so I looked at a lot of Bill Pressing's stuff. I also wanted a very jazzy look to it, and I think graphic shapes sort of embody jazz, so I also looked at Mary Blair. I like a lot of these and I think there is something in the black hair/black dress so I might do another color sketch of that one
