Color Temperature
The perceived color of a light source varies with the viewer and other conditions. Color
temperature is an objective measure of the color of a light source, defi ned with ref-
er ence to the temperature to which an object would have to be heated to radiate light
in the same wavelengths. While light sources with a color temperature in the neigh-
bor hood of 5,000–5,500 K appear white, light sources with a lower color tem per a ture,
such as incandescent light bulbs, appear slightly yellow or red. Light sourc es with a
higher color temperature appear tinged with blue.
