Standard 8/e is of course Amber and Terra Cotta. I've seen 8/F and 8/L
in that color scheme, as well as Orange and Terra Cotta for the 8/M.
Less standard color schemes for which i do not know the official color
names are the Industrial-8 colors (red and dark-blue), and another
8/e in light-blue and dark-blue.

The standard pdp/11 front panel colors are magenta and
wild rose.
From memory the 8/e front panel is mustard and
burnt orange
Each DEC computer family in the 60's / early 70's had their own
color. The LINC/PDP-12 was light and dark green, the 9 was a different
shade of orange than the 8/e, and the 15's were light and dark blue,
which was different from the PDP-10 blue.
