I'm trying to pick say 0,0,3 on sRGB and the values don't stick.
Selecting other combinations below also don't work.
Only when I pick a value above sRGB 0,0,15 + it works but jumps to 0,0,21 on re-open of the pallette.
Hue or saturation don't seem to affect this.
Also percent is affected and value 0-1.
