For RGB/CMYK color reference, I talk about absolute colors given by a 
publisher or a client. That's why I also like tools like the 'Specific 
color mixer' to set it.

* In RGB, often for web and video games, I receive them as a Hex color 
number ; and it's often to match a graphic color chart.

* For CMYK, I receive more the kind of indication  like this for a green :
C:50% M:0% Y:100% K:0%
or more rarefully , with 0-255 as Krita 'specific color selector' manage :
C:127 M:0 Y:255 K:0
This is often for a publisher with already the color of background for 
book cover, or a color chart used in their product.
I did some postcard works with this kind of constrain about fixed 
background CMYK hue.

It sound painfull to add , but that would be a very confortable feature 
to use it.
(on the long term )

Oh, I see. Not evident. May be red, then a pref for user to set the 
color he likes, ( or the color his system use for selected item )

>> * For artistic color choice, I dream about having something similar of
>> this gammut mask selector :
>> http://www.livepaintinglessons.com/gamutmask.php , A good book for
>> reference about painters and colors is
>> http://www.amazon.fr/Color-Light-Guide-Realist-Painter/dp/0740797719
>> This color selector in developement make me think a lot about it, and
>> the research of James Gurney (the author of the book).
> :D I have this book here on my desk :D
> I definitively will add support for gamut masks (this was one of my main
> goals).
Cool ! Btw, I will receive Framed Ink this week :)
Thanks for gave me the ref of it during the sprint , this book looks to 
contain really precious tips.
