Dealing with symbolism in Homestuck is a sticky business because even though it deals so heavily with duality, it also leans heavily on Gnostic combining-of-opposites imagery. A character can be aligned with white and green from one angle, but associated with red and black when you look at it from the other way. This is particularly prominent surrounding Caliborn/Lord English and Calliope/the Dead Cherub, who deliberately obfuscate duality in a distinctly Cherubic way by jacking each other’s swagger at every possible opportunity. It’s all a bit like a Mind player making meaningless coin flips just to prove a point.
Even this post is subject to a similar phenomenon. While I try to read it as “Homestuck is deliberately confusing because it concerns itself heavily with the Gnostic concept of syzygy,” another person would probably see it as “Homestuck has very little symbolic value at all and you are wasting your time trying to make sense of it.” They’re both true!
