“You asked me to explain why I am afraid of a draught of cool air; why I shiver more than others upon entering a cold room, and seem nauseated and repelled when the chill of evening creeps through the heat of a mild autumn day. There are those who say I respond to cold as others do to a bad odour, and I am the last to deny the impression. What I will do is to relate the most horrible circumstance I ever encountered, and leave it to you to judge whether or not this forms a suitable explanation of my peculiarity.”–H. P. Lovecraft

“As with sounds, so with colours. At each end of the solar spectrum the chemist can detect the presence of what are known as ‘actinic’ rays. They represent colours — integral colours in the composition of light — which we are unable to discern. The human eye is an imperfect instrument; its range is but a few octaves of the real ‘chromatic scale.’ I am not mad; there are colours that we cannot see.”
