Display approximation, not spectral measurementThe algorithm maps black-body temperature to an approximate sRGB color for visualization. Real lamps, camera white balance, displays, and measured spectra can differ.

Reverse estimation finds the nearest color in this display approximation; it is not a spectral correlated-color-temperature measurement.

Approximation boundary. This tool maps Kelvin to an approximate on-screen sRGB color using the same widely used piecewise black-body fit as the existing converter. It is useful for design previews, lighting references and white-balance context, but it is not a calibrated Planckian-locus/CIE measurement. Real lamps, display profiles, camera transforms, ambient light and spectral power distributions can differ. D50/D65 labels here are practical reference cues, not proof of standards-compliant white-point chromaticity.

Color and accessibility boundaries

HEX/RGB/HSL/HSV/OKLCH conversions are numerical color-model operations. CMYK output is an RGB-derived approximation rather than ICC-profiled print proofing. WCAG contrast ratios measure luminance contrast only and do not certify a full interface. Color-blindness previews are design simulations, not medical tests.

How to use Color Temperature to RGB

Enter a black-body color temperature from 1000K to 40000K or use a lighting preset to preview an approximate display color.

Important limit

This is an sRGB visualization approximation. It is not a spectral-power-distribution calculator, lamp measurement, ICC transform, or camera white-balance calibration.
