Color Temperature

  • mail
Color Temperature A method of expressing light from a light source. Expressed in K (Kelvin) units. When an object emits light, its color temperature is determined by using the temperature of a blackbody that emits the same light as this object’s light. Blackbodies, which are ideal emitters, become reddish like metal does when the heat is applied, and then gradually turn bright white. Therefore, the higher the color temperature, the cooler the color of light (blue), and the lower the color temperature, the warmer the color of light (red). The color temperature of sunlight at midday is approximately 5,500K. The color temperature of incandescent light bulbs is approximately 2,700K, and the color temperature of fluorescent light is approximately 6,000K. These are generally noted as slightly higher than the actual temperature.
