Re: [css-color] . 12-Bit deep color support.

Question: Why not just use rgba + percentages, to have future-proof color declarations?

With upcoming 4K and OLED monitors, with 10 Bit support, it eventually would make sense to extend the web-colors to 12 Bit.

Currently webcolors are defined 8 Bit – ‘web’ sRGB (like: #FFFFFF or rgba(255,0,0,1) )

So I propose adding something like 12-Bit ‘extended-web’ sRGB where you define colors like:
X#FFF FFF FFF - instead of #FF FF FF
Xrgba(255*16,0,0,1) - instead of rgba(255,0,0,1)

Supporting just 10 Bit (what is actually just needed by upcoming displays), would be quite difficult because of the poor 8+2 Bit format,

so the color white would be X#8FF - instead of X#FFF or #FF
