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:
“It seemed a long way from 143rd Street. Shaking hands with the Queen of England was a long way from being forced to sit in the colored section of the bus going into downtown Wilmington, North Carolina. Dancing with the Duke of Devonshire was a long way from not being allowed to bowl in Jefferson City, Missouri, because the white customers complained about it.”
—Althea Gibson (b. 1927)
“If twins are believed to be less intelligent as a class than single-born children, it is not surprising that many times they are also seen as ripe for social and academic problems in school. No one knows the extent to which these kind of attitudes affect the behavior of multiples in school, and virtually nothing is known from a research point of view about social behavior of twins over the age of six or seven, because this hasn’t been studied either.”
—Pamela Patrick Novotny (20th century)
