1970's CDC terminals had blue and red keys, IIRC.
It's been a long
time since I've seen one. I don't recall if the original plasma
PLATO terminals did--anyone recall?
I think the plasma ones and the raster ones both had colored keys.
They also had special keys for things like "answer", "help" and
so-on.
It was all very custom.
