What Is The Color Temperature?

When a black-body is heated to a temperature, and the color of black-body emitted is the same as the color of the light emitted by a particular light source, the temperature at which the black body is heated is called the color temperature of the light source, that is, the color temperature.

The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of comparable color to that of the light source.

When the standard black body is heated, the color will start from deep red->light red->orange->white->blue light when the temperature rises to a certain level.

In the era of traditional light sources, the color temperature difference between the light sources is 150K, and it is easy for the human eye to find the difference between them, but now the LED era is different.

Warm white color

Color Greenish
It is obvious that the above two colors are different. The light spot on the left is white, while the light on the right is green.
So what are their color temperatures? Is there a difference of 150K? Don’t worry, please refer to the following data:

CCT = 3061K

CCT = 3078K
▲ According to the data, the difference between these two color temperature is only 17K, and not as large as 150K.
Some people may doubt that why their color temperature difference is too less, but the human eye can see the difference in light color between them?
