Color temperature is a parameter describing the color of a visible light source by comparing it to the color of light emitted by an idealized opaque, non-reflective body, known as a black body. The te
The house above appears a light cream during midday, but seems to be bluish white here in the dim light before full sunrise. Note the color temperature of the sunrise in the background.

…describing the color of a visible light source by comparing it to the color of light emitted by an idealized opaque, non-reflective body, known as a black body. The temperature of the ideal emitter that matches the color most closely is defined as the color temperature of the original visible light source. The…
A black body radiator used in CARLO laboratory in Poland. It is an approximation of a model described by Planck's law utilized as a spectral irradiance standard.
