Question 1

What is color temperature?

Accepted Answer

Color temperature is a way to describe the light appearance provided by a light source, measured in Kelvin (K). Lower values (1000-3000K) produce warm, yellowish light, while higher values (5000K+) produce cool, bluish light.

Question 2

What is the Kelvin range?

Accepted Answer

Common color temperatures range from about 1000K (candlelight) to 40000K (deep blue sky). Daylight is around 5500-6500K. Indoor lighting is typically 2700-3500K.

Question 3

How accurate is the conversion?

Accepted Answer

The conversion uses the Tanner Helland algorithm which is widely used in photography and lighting applications. It provides a close approximation suitable for most design and web development purposes.

Question 4

Can I use these colors in CSS?

Accepted Answer

Yes. The tool outputs HEX, RGB and HSL values which can all be used directly in CSS. Click the copy button next to any value to copy it to your clipboard.
