Is your feature request related to a problem? Please describe.
Dragging the RGB sliders around is repetitive.

Describe the solution you'd like

• Initialize the color to... something not black. Maybe the Minecraft map-color for the block. Maybe random.
• A text field for editing the color in #xxxxxx form, both as workaround to the whole bunch-of-number config issue and as a way to allow for pasting in random pretty colors.

Describe alternatives you've considered
It's just convenience, so literally everything is an alternative.

Additional context
Uh, something like this. Maybe.
