Color temperatures are measured in Kelvin (K).
Color temperatures are typically measured in Kelvin (K). To understand how color temperatures are measured, you need to know about the concept of thermodynamic temperature.
Thermodynamic temperature is a scale for measuring temperature that is based on the behavior of particles, such as atoms or molecules. The Kelvin scale is a unit of measurement for thermodynamic temperature. It is an absolute temperature scale, meaning it starts at absolute zero (-273.15 degrees Celsius) and is measured in increments called kelvins (K).
Color temperature is a characteristic of light sources, such as light bulbs or computer screens. It describes the color appearance of light based on its temperature. The term "color temperature" comes from the fact that, as the temperature of an object increases, its color changes.
In the context of light sources, color temperature is the temperature at which a theoretical black body radiates light of a specific color. A black body is an object that absorbs all incident radiation and emits radiation at a particular temperature. The color temperature of light is often described using the Kelvin scale, where lower temperatures correspond to warmer, reddish light, and higher temperatures correspond to cooler, bluish light.
To measure the color temperature of a light source, specialized instruments called spectrometers or colorimeters are used. These devices detect the spectral distribution of the light emitted by the source and then analyze it to determine the color characteristics, including the color temperature.
So, to answer your question, color temperatures are measured in Kelvin (K).
