Use case or problem
I want to make a certain subset of nodes one color, and another subset of nodes a gradient of the same color.
I create a color group, choose the color, switch to the HEX view, and copy the code of the color.
Then I create another group, switch to the HEX view, and when I try to paste the code of the color, nothing happens. I tried to paste the code from a document, still nothing. The field does not seem to support pasting, so I have to write the code manually.
Proposed solution
Copy/Paste should be enabled for the HEX color field. There could also be a button to copy the color in the color-picker window.
Additionally, the selected color mode (RGB, HSL or HEX) should be remembered. Currently, every time you open the color window of a group, the RGB mode is always displayed.
