Color Temperature Converter

Color Temperature Converter - Translate Kelvin Into Color Values Instantly

Lighting designers, photographers, and UI teams often need fast Kelvin-to-color lookups. This converter turns any color temperature between 1,000K and 40,000K into real-world HEX, RGB, and HSL values while highlighting whether the light feels warm, neutral, or cool. Use it to align brand palettes with lighting environments, preview LED presets, or prep color grading sessions.

How does Kelvin relate to color?

Kelvin (K) measures the color temperature of light. Lower values (2,500K–3,200K) appear warm and amber, mid values (4,500K–6,500K) feel neutral daylight, and higher values (8,000K+) look cool and blue. By converting Kelvin to RGB/HEX we can simulate that light on screens.

What can I do with the conversions?

Copy HEX, RGB, or HSL to style UI themes, 3D renders, lighting guides, or photo color grading LUTs. Use the luminance reading to balance accessibility contrast, and reference the suggested uses to match ambience with your project mood.

Why are the ranges limited?

Most creative workflows sit between 1,000K candlelight and 40,000K bright sky. Outside that range, approximate RGB values become unreliable on SDR displays, so we clamp to realistic lighting temperatures for consistent results.
