How to light up the cold light in photography?

Cold in photography refers to color temperature, which has important applications in photography, video recording and publishing. The color temperature of the light source is determined by comparing the color of the light source with the theoretical hot blackbody radiator. The Kelvin temperature when the hot blackbody radiator matches the color of the light source is the color temperature of that light source, which is directly related to Planck's law of blackbody radiation. The standard candle light is 1930K (kelvin-day); Tungsten lamp 2760-2900K；; The fluorescent lamp is 3000 k; Flash 3800 k; The sunshine at noon is 5600 k; Electronic flash 6000 k; The blue sky is 12000- 18000K. There is also color enhancement.
