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 5000–5500 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. The camera white balance options are adapted to
the following color temperatures (all figures are approximate):

I (sodium-vapor lamps): 2700 K

J (incandescent)/
I (warm-white fluorescent):
3000 K

I (white fluorescent): 3700 K

I (cool-white fluorescent):
4200 K

I (day white fluorescent): 5000 K

H (direct sunlight): 5200 K

N (flash): 5400 K

G (cloudy): 6000 K

I (daylight fluorescent): 6500 K
