This is real:

Fripp: That D major chord which changed you from a pianist to a guitarist, what color would that be for you?

McLaughlin: What color...? (pause) I think it could be green.

Fripp: Exactly what I would've said...

McLaughlin: It's got to be yellow and some blue.

Fripp: A major for me is yellow and A minor inclines toward white, which is my C major. Graham Bond said it was red.

McLaughlin: C major, red? No, E major, I would say, is red.

Fripp: E major for me is very blue, a kind of royal blue, and when you get to E minor it becomes more of a night blue, with kind of stars...

McLaughlin: That's very interesting...

Fripp: G is very greenish, but not quite.

They're all wrong.

D major is a strong and heavy arrow. E minor is a sad rectangle. C major is holding on. A minor is giving in. G major is an open door. A major is the closed door. Diminished chords are covered in spines.
