Colors are calculated using the Tanner Helland algorithmbased on Mitchell Charity's blackbody radiation data. Results are approximate sRGB values — actual perceived color depends on your display calibration. D65 (6500K) is the standard white point for sRGB monitors and most digital photography.

Common Use Cases for the Color Temperature Converter
Photography & Videography
Match your camera white balance setting to the actual color temperature of your light source. Use the converter to find the exact Kelvin value for golden hour, overcast, or studio lighting.
Lighting Design
Specify the correct color temperature for architectural and interior lighting projects. Compare warm (2700K), neutral (4000K), and cool (6500K) options side by side.
Monitor Calibration
Understand the D65 (6500K) standard white point used for sRGB monitors and digital photography. Verify that your display is calibrated to the correct color temperature.
UI Design & Color Grading
Generate warm or cool color overlays for UI themes, photo filters, and video color grading. Use the HEX output directly in CSS or design tools.
Retail & Product Photography
Choose the right color temperature for product photography to ensure accurate color reproduction. Most product photography uses 5000K–5500K for neutral, true-to-life colors.
Developer & CSS Work
Generate CSS color values for color temperature effects, night mode implementations, and adaptive lighting UIs. Copy HEX and RGB values directly from the converter.
Understanding Color Temperature
What is Color Temperature?
Color temperature describes the color of light emitted by a theoretical perfect radiator (a blackbody) heated to a given temperature in Kelvin (K). Lower temperatures (1000K– 3000K) produce warm orange and yellow light, similar to candlelight or incandescent bulbs. Higher temperatures (5000K–10000K) produce cool blue-white light, similar to daylight or a clear sky. Our color temperature convertertranslates any Kelvin value into its approximate sRGB color using the Tanner Helland algorithm, which is based on Mitchell Charity's blackbody radiation data.
How Our Color Temperature Converter Works
- Enter a Kelvin Value: Type any temperature between 1000K and 10000K into the input field, drag the slider, or click a preset light source. The converter updates instantly in your browser.
- Instant Color Calculation: The Tanner Helland algorithm computes the approximate sRGB red, green, and blue channel values for the given temperature. The result is displayed as a color swatch with HEX and RGB values.
- Copy and Use the Result: Copy the HEX or RGB value to your clipboard for use in CSS, design tools, or lighting specifications. Click any point on the Kelvin scale to explore the full range.
Key Color Temperature Reference Points
- 1800K — Candlelight: Deep orange glow. The warmest light source in common use. Creates a very warm, intimate atmosphere.
- 2700K — Incandescent: Warm white. The classic light bulb color. Standard for residential lighting in most countries.
- 5000K–5500K — Daylight: Neutral white. The standard for photography, printing, and color-critical work. Matches natural sunlight at noon.
- 6500K — D65 Standard: The reference white point for sRGB color space and most digital displays. Used for monitor calibration and digital photography standards.

Frequently Asked Questions About the Color Temperature Converter
A color temperature converter translates a Kelvin temperature value into its approximate RGB and HEX color. It uses the Tanner Helland algorithm based on blackbody radiation data to calculate the sRGB color that corresponds to a given light source temperature. Our converter runs entirely in your browser.
Kelvin (K) is the unit used to measure color temperature — the color of light emitted by a theoretical perfect radiator at a given temperature. Lower Kelvin values (1800K–3200K) produce warm orange-yellow light. Higher values (5000K–10000K) produce cool blue-white light. 6500K is the standard daylight reference point.
D65 (6500K) is the standard illuminant used as the white point for the sRGB color space, most digital displays, and digital photography. When your monitor is calibrated to D65, colors appear as intended by the content creator. It represents average midday daylight in Western Europe.
The Tanner Helland algorithm provides a good approximation of blackbody radiation colors for the 1000K–40000K range. Results are accurate to within a few percent of the theoretical values. The actual perceived color also depends on your display calibration and ambient lighting.
For neutral, accurate color reproduction, use 5000K–5500K (noon daylight). For warm, golden-hour looks, use 3200K–4000K. For cool, overcast looks, use 6500K–7500K. Most cameras let you set white balance in Kelvin — use this converter to find the exact value for your lighting conditions.
Warm light (below 3500K) has a yellow-orange cast and creates a cozy, intimate atmosphere. Cool light (above 5000K) has a blue-white cast and creates a crisp, energetic atmosphere. Neutral light (3500K–5000K) appears white and is used for task lighting and color-critical work.
