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.
"Warmer" (redder) colors
3000
In general, choose lower values if your pictures have a red cast or to
intentionally make colors colder, higher values if your pictures are
tinged blue or to intentionally make colors warmer.
