[Feature suggestion] Ability to change label color

[fabien-joubert]

As far as I know there is no way to change the label color (left part).

I think it might be a great feature to be able to add &label_color=FFFFFF to further customize the counter.
FFFFFF: the value of the color in hex.

I don't have enough time for that at the moment.
