[RP] status bar: color-by-window?

[Joe Corneli]

Am I correct in remembering that back in the day
individual lines could be given different colors?
If so, is this feature still alive or possible?  Or
is an external application suggested for this purpose?
I'd like to highlight windows e.g. by regexp.

Thanks ratpoisonistas!
