Assign a color to an environment

Just as in Insomnia, I would find it very useful to be able to assign a color to a workspace. I have the habit to set my local as green and production as red, and it really helps to see in a glance if I am about to do something by mistake.

As a plus, it would be even better if the color would somehow become an accent, or more visible than just a glyph next to the name of the workspace. It could become the color of some borders, some text, the title bar, … I don't really know what is possible or not to keep it consistent with the themes and the technologies behind
