In nature, colors average 4 parts black to 1 part white.Strange times are these in which we live, when old and young are taught in falsehoods school. And the one man that dares to tell the truth is called at once, a lunatic and fool. - Plato

Middle Gray Isn't

In nature, colors average 4 parts black to 1 part white.

Our eyes are sensitive to different colors and to gray in different degrees.

Gray

It turns out that the color we usually think of as gray is not half way between black and white. It is actually far darker than you would guess. This gray is actually 4 parts black and only 1 part white.

This corresponds with some research done by Jones and Condit at Kodak in 1941 which found that the average scene in nature is about 4 parts black to 1 part white.
