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, defined with reference 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 neighborhood of 5,000–
5,500 K appear white, light sources with a lower color temperature, such as incandescent light
bulbs, appear slightly yellow or red. Light sources with a higher color temperature appear
tinged with blue.
