Color temperature is one physical quantity used in illumination optics to define the color of a light source. That is, a black body is heated to a temperature at which the color of light emitted from the black body is the same as the color of light emitted from a light source, and the temperature heated by the black body is called the color temperature of the light source, which is called color temperature for short. The units are expressed in "K" (Kelvin temperature units).
Color temperature (colo (u) elementary features) is a characteristic of visible light that has important applications in the fields of photography, video recording, publishing, etc. The color temperature of a light source is determined by comparing its color to a theoretical thermal black body radiator. The kelvin temperature at which a thermal black body radiator matches the color of a light source is the color temperature of that light source, which is directly related to planck's black body radiation law.
The color temperature is below 3300K, and the color of the light is reddish, so that the user feels warm; has a steady atmosphere and a warm feeling, which is known as warm color temperature.
The color temperature is in the middle of 5000-6000K, and people have no particularly obvious visual psychological effect and have a refreshing feeling under the color tone; so called "neutral" color temperature.
