Is is possible to change the belt colour to match the belt type?

E.g. If a express transport belt is selected, the belt visual will be blue.

I've tried this before, but other colors do not look good when used as highlight colors. I'm not against the idea, but if I do end up doing something I would have to add support for modded belt colors as well, and that would be a pain to maintain.

What about an option for users to change the color?

I suppose that would be fairly easy, though good luck finding something that contrasts more than yellow

I've tried this using map colors and with "custom map color" mod and I can teel this seems a good idea but looks messed up (even with high contrast blue and red)
