Examples of color temperatures

The color temperature of a light source is determined by comparing the chromaticity with the radiation of a black body. The color temperature is equal with the radiation value of a hot black body, measured in Kelvin (K), which is the same as the color source of the light.

The high color temperatures (over 6000 K) correspond with the cold colors (green-blue) and the lowered color temperature with the hot colors (yellow-red).
