Light color is described by its color temperature, measured in Kelvin (K). The concept originates from the physical property of “black body” radiation—when a black body is heated, it glows in colors that change as the temperature rises: red, yellow, and finally white. This chromatic shift forms the basis of our perception of color temperature in lighting.
- Warm Light: Characterized by a color temperature under 3000 K, emitting red, orange, or yellow hues, warm light creates a cozy and tranquil atmosphere.
- Cool Light: Typically has a color temperature exceeding 4000 K, producing a bluish-white glow reminiscent of daylight or an overcast sky.
