Kelvin Scale

Color Temperature: is a description of the color of visible light from a light source. In Photography this is measured on a scale of degrees Kelvin. The higher the color temperature the cooler the color (blue-white); the lower the color temperatures the warmer the color (yellow-white through red). The Kelvin scale goes from 1000 to 10,000, with 1000 being very warm and 10,000 being very cool.

A common misconception is some perceive this scale in reverse, which comes from unguided experimentation in setting the white balance manually in the camera.
