There is a method in NSColor to do just that. Check it out.

---------------------------

colorUsingColorSpaceName:

- (NSColor *) colorUsingColorSpaceName: (NSString *) colorSpace
Creates and returns an NSColor whose color is the same as the 
receiver's, except that the new NSColor is in the color space named 
colorSpace . If colorSpace is nil , the most appropriate color space is 
used.

Returns nil if the specified conversion cannot be done.
