Color temperature is a unit of measurement that expresses the color components contained in light. Theoretically speaking, the black body temperature refers to the color of the absolute black body after being heated from absolute zero (-273°C). After the black body is heated, it gradually turns from black to red, turns yellow, turns white, and finally emits blue light. When heated to a certain temperature, the spectral component of the light emitted by the black body is called the color temperature at this temperature, and the unit of measurement is "K" (Kelvin).
