Correlated Color Temperature (CCT) is a fundamental concept in lighting design that quantifies the color appearance of light emitted by a source. It measures the warmth or coolness of light on a scale measured in Kelvin (K).

At lower CCT values, typically ranging from 2000K to 3500K, light appears warmer, with tones leaning towards red and yellow. This warm light is often associated with cozy, intimate settings, such as living rooms or restaurants, evoking a sense of comfort and relaxation.

Conversely, higher CCT values, usually between 4000K and 6500K, produce cooler light with bluish tones. This cooler light resembles daylight or overcast skies and is often preferred in workspaces, retail environments, and outdoor settings for its clarity and alertness-enhancing qualities.

Understanding CCT is crucial for selecting lighting that complements both the functional and aesthetic requirements of a space. It enables designers to create environments that not only meet practical needs but also evoke desired emotional responses and atmospheres. Whether aiming for a warm, inviting ambiance or a crisp, energizing environment, CCT serves as a valuable tool in achieving lighting objectives.
