Make Krita ready for Wide Gamut editing
Most consumer screens can only show a limited amount of colour, this we generally refer to as the sRGB space. Wide gamut editing is about editing values in larger spaces of colour(such as Adobe RGB or the ACES colour space) and emulating how that looks on the screen.
When this project was started, Krita’s architecture had all the bells and whistles for wide-gamut editing. Two big items were missing: Softproofing and a good internal colour selector dialogue for selecting colours that are outside of the sRGB colour space.
As of this time of writing, the Softproofing work is merged, and the internal color selector is still suffering from some bugs but will probably be merged the next time the merge window is open.
