Yeah, starting off with the primary color before using a plugin is a sort of workaround, but my mind thinks in hex rather than rgb, so it would be nice to just use hex while in a plugin's colorwheel. I often try this color and then that color and then another color, but all of them are hex values in my mind. Example: Maybe I want to use my standard #dddddd gray color for a shadow but then decide maybe #333333 would be better against this particular object. Those numbers mean something to me. I know what they look like in my head. I'd love to just drop them into a field (or a client's logo color that I have memorized), and try various things while in the plugin's color wheel area. Since it's already in the main color wheel, seems like a natural extension to include it in the plugin control. I can live without it, but it would be awesome if it was there.
