Remember last color mode - color editor

[wayfaringrob]

It would help speed up my work if opening the color editor would remember the color mode I used last time. Ex. I have several colors in my symbology that I would like to brighten up by adjusting its value. The default, though, is RGB, adding another two clicks per symbol.

Those options aren't UI modes. They define the color type being authored and it will reflect the color type being edited. Since HSV is an alternative representation of the the RGB color model, some apps have UIs that show HSV selectors for colors they persist as RGB. We have an enhancement request to do this, but there are also still valid reasons for persisting just HSV values too so that will continue to be an option.
