Glossary: HUE

Often used synonymously with the term tint. It is the dominant wavelength, which distinguishes a color or tint as red or yellow, etc. Video hue is influenced by several factors: Adjustment of the white balance of the camera, quality of the electronic equipment which is being used and lighting of the scene. In the NTSC standard, hue errors are more common than in the PAL standard due to a different color encoding system. The PAL system compensates for color problems and it corrects wrong hues during operation. Video color processors are the main tools used to adjust and correct hue problems. For example, when videotape is shot in a green park there is a tendency for a greenish tint to dominate the whole scene, which should be removed in order to restore natural skin tones.
