Ucolor screen for any watch face

It would be great if there could be a simple screen in the app where you could select a ucolor for what ever watch face is currently on the watch itself.

I select faces from the watch itself often but want to change the ucolor value at the same time.

So it would be cool if there was a screen in the phone app of watchmaker or maybe in the face selector on the watch to change the color!

I know that I can change the color for the face currently on the watch just by pulling up any face in the app that uses ucolor.
