Color Temperature Converter

What is a Color Temperature Converter?

Convert color temperature values in Kelvin (`1000K` warm candle light to `40,000K` clear blue sky) into approximate RGB, HEX, and CSS color codes.

Why Use This Converter?

  • Photography & Lighting: Determine RGB color balances for warm tungsten (2700K), daylight (5500K), and cool shade (7500K) lighting.
  • UI & Game Design: Calculate realistic physical light source color values for shaders, 3D rendering, and UI themes.
  • Display Calibration: Understand blue light and night-mode screen color temperatures.

How to Use

  1. Drag the Kelvin slider or enter a value between 1,000K and 40,000K.
  2. View real-time visual color preview tile.
  3. Copy RGB or HEX color codes for your CSS or shader design.

Real Conversion Example

Input (TEXT):

6500K (Standard Daylight)

Output (TEXT):

HEX: #FFF9FD
RGB: rgb(255, 249, 253)
Light Source Equivalent: Standard Noon Daylight

Important Technical Details & Mechanics

  • Tanner Helland Algorithm: Uses Tanner Helland's physical blackbody radiation approximation algorithm for accurate Kelvin to RGB conversion.
  • Full Scale Range: Supports 1,000K (warm orange/red) up to 40,000K (deep blue).
  • 100% Browser Execution: Instant visual update as slider moves.

Frequently Asked Questions

What Kelvin temperature is standard daylight?

Standard daylight is approximately 5,500K to 6,500K.

What Kelvin temperature is warm indoor light?

Warm incandescent indoor light is typically 2,700K to 3,000K.

Are lower Kelvin values warmer or cooler?

Lower Kelvin values (1000K-3000K) produce warmer orange/red colors; higher values (7000K+) produce cooler blue colors.

Is it free?

Yes, 100% free and browser-based.
