What is the color temperature of the three primary color lamps?

Unit: Kelvin k. The color temperature of the three primary color lamps refers to when the color emitted by the light source is the same as the light color radiated by the black body at a certain temperature. The temperature of the black body is called the color temperature of the light source, generally expressed in Kelvin k. as unit. For example, 3200k and 5600k, etc. When the color temperature is high, the color of the light is cooler; when the color temperature is low, the color of the light is warmer; when the color temperature is moderate, the light is close to white. Under normal sunlight in nature, the color temperature of light is generally higher than the color temperature of artificial lamps. Under normal circumstances, the color temperature of sunlight is about 5600K, while the color temperature of studio and performance lamps is around 3200K. The color temperature required for video conference room lamps will be 3200K, 4000K, 5600K depending on the specific situation, usually 4000K, because 4000K The picture taken with the color temperature is the best, not reddish or white. Generally speaking, in hotels, the color temperature is generally 2700K, which is yellowish; in office lamps, which are civilian lamps, the color temperature is 6400K, and the color is whitish; while in KFC and McDonald's, the color temperature is 4000K, which is very soft and not dazzling.
