Re: [CSS Colors] gamma

Maybe I am being dense, but why do we have this section at all?

It seems that colors should be expressed in a known color space, and  
that if the output device or display has any different characteristics  
(e.g. different gamma, or is CMYK because it's being printed), then  
color space conversion needs to take place.
