Try setting the tone mapping to HSV Exponential in your render settings and see if that improves the color a little bit for you. That's assuming you have that option. I realize you're running Pro 2010 and I'm using 8, but I'll assume you have that.

The reason I'm suggesting this is because I've found that it saturates colors too much for my taste, but if you're in need of saturation, might be worth to at least try it...lol.

You might also try bagginsbill's VSS which will improve the skin a whole lot ;o).
