Color Temperature (CT)

Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, manufacturing, astrophysics, and other fields. It is expressed in Kelvin (K) using the Planckian locus – a visual plot of the spectrum of brightness and hue of different pure light sources. A lower color temperature indicates a more red/yellow hue while a higher color temperature indicates a more blue hue.
