The color of the Great Canon itself is red, a light Indian Red, and the material sandstone and red marble and is in terraces all the way down.

From our camp at the pocket the wall of the Grand Canon was visible some 15 miles down the valley.

When yellow lights struggle with blue shades in hairlike lines.

From around the corner's edge a grotesque light was trickling out, the first intimations of an ominous sunrise over a dark horizon. I dimly recognized this colored light, though not from my waking memory. It grew more intense, now pouring out in weird streams from beyond the solid margin of the building. And the more intense it grew, the more clearly I could hear the screaming voice that had called out to me in a dream. I shouted his name, but the swelling colored brightness was a field of fear which kept me from making any move toward it. It was no amalgam of colors comparable to anything in mortal experience. It was as if all natural colors had been mutated into a painfully lush iridescence by some prism fantastically corrupted in its form; it was a rainbow staining the sky after a poison deluge; it was an aurora painting the darkness with a blaze of insanity, a blaze that did not burn vigorously but shimmered with an insect-jeweled frailness. And, in actuality, it was nothing like these color-filled effusions, which are merely a feeble means of partially fixing a reality uncommunicable to those not initiated to it, a necessary resorting to the makeshift gibberish of the mystic isolated by his experience and left without a language to describe it.

I've stopped racing to get to the red light.
