A colour cast is a tint of a particular colour, usually unwanted, which affects the whole of a photographic image evenly.
Certain types of light can cause film and digital cameras to have a colour cast. In general, the human eye does not notice the unnatural colour, because our eyes and brains adjust and compensate for different types of light in ways that cameras cannot.
In film, colour casts can also be caused by problems in development. Improper timing or imbalanced chemical mixtures can cause unwanted casts.

Famous quotes containing the words colour and/or cast:
“Iconic clothing has been secularized.... A guardsman in a dress uniform is ostensibly an icon of aggression; his coat is red as the blood he hopes to shed. Seen on a coat-hanger, with no man inside it, the uniform loses all its blustering significance and, to the innocent eye seduced by decorative colour and tactile braid, it is as abstract in symbolic information as a parasol to an Eskimo. It becomes simply magnificent.”
—Angela Carter (1940–1992)
“For those who are base in judgement do not know the good they hold in their hands until they cast it off.”
—Sophocles (497–406/5 B.C.)
