Color Difference
The difference or distance between two colors is a metric of interest in color science. It allows people to quantify a notion that would otherwise be described with adjectives, to the detriment of anyone whose work is color critical. Common definitions make use of the Euclidean distance in a device independent color space.
Famous quotes containing the words color and/or difference:
“All our Concord waters have two colors at least; one when viewed at a distance, and another, more proper, close at hand.... Walden is blue at one time and green at another, even from the same point of view. Lying between the earth and the heavens, it partakes of the color of both.”
—Henry David Thoreau (1817–1862)
“If you pick up a starving dog and make him prosperous, he will not bite you. This is the principal difference between a dog and a man.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
