Frequently Asked Questions
Roughly 1000K-40000K covers real-world references — candlelight is around 1900K, warm incandescent bulbs around 2700K, daylight-balanced light around 6500K, and overcast sky/shade tends toward 8000K+ with a blue tint.
It uses a well-known mathematical approximation of black-body radiation color (not a real spectrophotometer measurement), verified against expected reference points: warm orange-red at low Kelvin, near-neutral white around 6600K, and blue-tinted at high Kelvin. It's a close visual approximation, not laboratory-precise.
Estimating what a given color temperature (from a camera white-balance setting, a light bulb spec, or a lighting design brief) looks like as an actual displayable color.
