A white point (often referred to as reference white or target white in technical documents) is a set of tristimulus values or chromaticity coordinates that serve to define the color "white" in image capture, encoding, or reproduction. Depending on the application, different definitions of white are needed to give acceptable results. For example, photographs taken indoors may be lit by incandescent lights, which are relatively orange compared to daylight. Defining "white" as daylight will give unacceptable results when attempting to color-correct a photograph taken with incandescent lighting.

Famous quotes containing the words white and/or point:
“Then came Corinna in a long loose gown,
Her white neck hid with tresses hanging down,
Resembling fair Semiramis going to bed,”
—Ovid (Publius Ovidius Naso)
“The town is divided into various groups, which form so many little states, each with its own laws and customs, its jargon and its jokes. While the association holds and the fashion lasts, they admit nothing well said or well done except by one of themselves, and they are incapable of appeciating anything from another source, to the point of despising those who are not initiated into their mysteries.”
—Jean De La Bruyère (1645–1696)
