So: I haven't given up on this, but also I'll admit I'm more than a little stymied. (Obviously, since it's mid-January and I'm still working on it.) Can you confirm that the white arrow means (following in rot13 for spoilers)
ghea gur jbeq vagb nabgure jbeq va vgf pngrtbel, fb gung "gba" -> "cbhaq" (jrvtugf) naq "cbhaq" -> "rheb" (pheerapl
though if that's right, I don't know what's below "hear" (I'm assuming that "two parallel arrows" means "you can use this transformation in two different ways to get from A to B". Like, "read -> lead" could be connected with two arrows that mean "rhyme", because they rhyme as present-tense/opposite-of-follow and also as past-tense/metal-element.)
The problem I'm hitting is that there's no independent evidence for orange and blue, only for them together. I want, based on the above, for

Want to offer a nudge in the right direction?
