@starling: ”Did I miss any?”

For simplicity, you could lose the numbers and go with purple in place of pink 1, letting pink 2 be simply ‘pink. Having used black, you could use white for unions & labor activists, then use the blue for the academics. Blue fits their message & mood, and would save the confusion of red & crimson being more or less the same color.

Having critiqued as per invitation, now let me compliment you on the brilliance of the whole scheme!

Oh, ‘burnt orange’, using an adjective when none of the others do, could be brought into line by going instead with brown, which is not a bad choice for a bunch of assholes.
