Well, Green was for 6 volt filaments, Yellow was for 5 volt filaments, Red for B+, Grey was for A.C. mains, White was for I.F., yellow was for cathodes, and black was for B- which was sometimes but not always the chassis ground. Striped colors were usually for center taps of power transformers ( on any windings) or bias battery leads, blue and brown were many times output transformer plate connections, and white and purple was reserved for "other." Output transformer secondaries were equally obfuscated, but generally the black was at B- potential or ground, and yellow was 4, green was 8 ohms, and after that it's anyone's guess.

Nobody followed the standards faithfully, and after all those years, most of the colors have faded anyway.

I'm sure someone will come up with a better list, if that helps.
