I often have many tabs open in Core Shell. I use different color terminal backgrounds to help me avoid typing things into the wrong machine (!) - red for production, for example. It would be useful to be able to color tabs so that I can click on the right one first time.

Wonderful idea! But set background colors for tabs are kind of dazzling, may be tint the favicon is a better solution.

You could let the user decide - perhaps some people like dazzling

I still think it would be good to let the user decide whether to have coloured tabs or not...
