Other Color options besides light and Dark theme

For reasons specific to the type of work that I do, I have all three of the Edge Insider browsers installed (Canary, Dev, and Beta). I think it would be helpful for me and others if we could choose a color other than light and dark to make telling the browsers apart visual much easier. This would be purely a cosmetic change. Also the icons for Dev and Beta are extremely similar. I also think they could use a bit of differentiation as well. I'm sure others who are testing\developing with multiple version of the browser would also appreciate these changes
