Color Temperature Converter
Convert any color temperature in Kelvin to its corresponding RGB and HEX color — from warm candlelight (1900K) to cool daylight (6500K) to icy blue sky (10000K).
What Does This Tool Do?
Uses the Planckian locus approximation to convert a color temperature in Kelvin to the closest visible RGB/HEX color. Useful for lighting design, photography white balance, and display calibration.
Key Features
How to Use This Tool
- Enter a Kelvin value or choose a preset.
- Click Convert to see the corresponding color.
- Copy the HEX, RGB or HSL values.
How It Works
Uses Tanner Helland's Planckian locus approximation algorithm which fits a polynomial to the black body radiation curve for the range 1000K–40000K.
Common Use Cases
Frequently Asked Questions
What is 6500K?
6500K (D65) is the standard white point for sRGB monitors and daylight. Candles are ~1900K (very warm orange). Overcast sky is ~7500K (slightly blue).
