Color temperature is measured in Kelvin, which is a unit that quantifies the color of light and provides a way to describe how 'warm' or 'cool' light appears visually. The Kelvin scale ranges from lower temperatures indicating warmer colors (such as reds and yellows) to higher temperatures corresponding to cooler colors (like blues and greens).

In lighting, a color temperature of around 2700K represents warm light similar to incandescent bulbs, while 5000K or above is often associated with daylight or cooler lighting. Understanding color temperature is essential in audio-visual contexts as it influences the mood and perception of environments, making it critical for designers and technicians to achieve the desired visual ambiance through appropriate lighting choices.

The other units listed serve different purposes: footcandles measure illuminance, Hertz is a measure of frequency, and Celsius measures temperature in the context of thermodynamics rather than light color. Thus, Kelvin is the correct unit for measuring color temperature.
