Just found this from Facebook via a link on a "Forgotten NY" article on route names. It's apparently an early version of the 1967 colors I never knew about or heard anyone else say they knew about!
On my linehistory page http://www.erictb.info/linehistory.html, I have at the bottom the evolution of the Chrystie St. plans that occured from 1961-7. By the 1966 plans, the same year this Unimark International company designed the new bullets:
The ![(QJ)]()
was already planned, but ![(T)]()
was to be retained (first, still on Bway in early phases of the plan, then finally, the 6th Ave. service to midtown only). So we see the ![(T)]()
was blue (dark blue, not future SAS turquoise). Of course, in the final plan, only the ![(TT)]()
was kept for a while, and that was what became that color.

5 is magenta instead fof black.
F looks black intead of magenta (but then B was still black as well. Same color is not supposed to run on the same line. Though looking closer at it, it looks more like a dark green!).
4 is green instead of magenta, which of course would be the eventual 1979 trunk color.
RR is black instead of green.
SS is light blue instead of green. (or any of the other colors used for various shuttles originally).
(1 and 6 look red, but they're really the same as the final colors as you can se in the lower pictures).
