Color picker added in commit ffeae24

By non-team I mean colours that aren't the RGBY of the squad's team colours, including diwako_dui_special_track objects, your buddy, and similar.

I would like to have the color defined with all other colors in the config, reason behind it, pretty much just coherence between future features.

But I can understand that you'd like to choose for your own, there is a CBA color picker, tho that would mean there is a need for RGB to Hex conversion. Right now I have hex to RGB. IIRC ace had some conversion for it, maybe can ask in their slack to """borrow""" their code.
Not sure right now.

To summarize:
Either predefined color, meaning you can suggest them, or color picker but needs a bit more code.

Colour picker would be ideal imo.
