Summary

After we release colorspace suite, we should follow up with color managed color parameter.

Example use cases:

set a red rectangle - user might think in terms of 1,0,0 but the actual given working process colorspace might not be intuitive.
pick somewhere on screen to get color somehow
set a threshold value slider
make your own custom widget (e.g. HLS)
map OS supplied color picker (some do that I think when you click on color param)

Problem

likely requires a host call back to return to us chromacites?...
perhaps color are always define in linear internally?
host might support different display options if they popup a color param editor for such param
