Assign colours to tagged drives

It would be great to be able to assign a colour to different tags to make it easier to identify them on the main day screen and in search results. For example I do occasional food delivery with my car and have a "DoorDash" tag, which I would like to set to be red and an "UberEats" tag which I'd like to set to be dark green. But I'm sure others would have a use for this too.
