Most cameras have a couple of color spaces to choose from. I use sRGB, which I find is easier to work with, in case I plan to print photos. Either can work, but I like the skin tones better from the sRGB color space, and the saturation of reds.
Your camera should come with sRGB set – just leave it that way.
