the first 'b' is still used in everyday life.
the second 'b' when it comes to scanning (or faxing if these machines are still around).
the 'g' is what i brought to high school and i felt like such a rebel.
the 'r' now makes perfect sense as it was strictly used to mark an A+ or on the other end of the spectrum a circled F.
so, what do i use now, pinks and turquoises .... take that 'standards'!
blue ~~ black ~~ green ~~ or red (pink and turquoise)
