What color temperature means

Color temperature describes the hue of a light source measured in Kelvin (K). Lower Kelvin values (1800–3000 K) appear warm/orange-yellow like candlelight or incandescent bulbs. Higher values (5500–12000 K) appear cool/blue-white like daylight or overcast sky. The conversion uses Mitchell's algorithm — a well-known approximation of the Planckian locus that matches real-world measured values within ~2%.

Use cases: choosing LED bulbs, white-balance photography, and matching screen color profiles. For design use, see Color Converter and Color Palette Generator.
