FITS, as such, doesn't have the concept of color space. People have  
found ways of using fits to hold RGB images and the like, but  
generally, a FITS image is usually taken through one filter. It's  
usually up to someone to combine images from different filters into a  
color image. But perhaps you have one of these "color" images already.  
If so, where did you get it? What does the header show?
