Just to make sure:

KisColor should internally be based on XYZ (or lab), but not RGB. This to 
provide the largest possible gamut.

The colorchooser should provide different colormodels for specification but 
should always store in KisColor and thus in XYZ (or lab).

The user should have several ways of specifying color. In my mind it should be 
a limited set including hsv and rgb, but in special cases like gray and with 
substance channels we should provide a colorspace specific chooser. I don't 
know if this is needed for YUV, but perhabs we should always provide the user 
with rgb,hsv, plus the specific colorchooser, with the option of disabling 
rgb and hsv if it doesn't make sense (as in gray).

KisPixel should be based on whatever colorspace the associated canvas is.
