A specification of a light source's hue, expressed in degrees Kelvin. Lower numbers are more red or orange, and higher temperatures are more blue. Almost all stage/studio tungsten-halogen lamps are 3200K. Most discharge lamps used in moving lights and followspots are 5000-6000K.
Color Correction filters, various saturations of CTO and CTB may be used to alter a source's apparent color temperature, but always at a loss of intensity.
Balancing color temperatures is much more important in photography, film, and video than live performance, as the human eye is more forgiving and adaptable than the camera.
For more, see Kelvin Color Temperatures and/or Understanding White Balance.
