I can try red and green, but metallic is tough; metal reflects differently than stone, so the surface texture won't look quite right for metal. I can try a few blending options though, that might help, but no guarantees. And keep in mind, there are two other color schemes in front of you.

edit: Also, I have doubts how well red/green would go with blond hair; I may make her a brunette, and I'm considering green eyes. If it doesn't matter, great, but make sure to post here if you don't want those changed.
