Watercolor Study in D5 (power chord) No. 1

A short study of the D5 power chord — D and A, root and fifth, nothing else. D gives the orange ground, A the yellow-orange, and the line falls from the high register down toward the black of the bass. Where you see green, that is my deuteranopia at work: the hand mixing what the eye reads as yellow-orange. I leave it as it is. The codex sets the rule, my own eye bends it, and that bend is part of the game I have to assume.
