(VLR Spoilers) Something cool about the flowchart

So I just noticed you can find a path with a white door by choosing two complimentary-colored chromatic doors (allying/betraying aside).
So...
Magenta --> Green --> White
Yellow --> Blue --> White
Cyan --> Red --> White
I bet someone's mentioned this at some point, but this is the first I've seen it and I thought it's pretty cool how it ties in the whole complimentary colors make white concept, but with the doors you choose.
