Do You See What I See?
“One has the feeling that Gordon Bell will eventually begin to record his reviewing of his record of his experiences, setting him in an endless loop terminating only when his registers overflow.”
—David Hopp - Durham, N.C.

Colorful Origins
According to “Illusory Color and the Brain,” by John S. Werner, Baingio Pinna and Lothar Spillmann, an object’s color is made relatively stable by the brain despite environmental changes. I am partially color-blind and have observed that when looking at a particular object in natural light, the vividness of its color will be affected by my proximity to it. Furthermore, in my trade as an electrician, I have found that the use of a flashlight shined on color-coded wires at close range assists in their discernment.
