Color Temperature Adjuster
Choose a base HEX color and adjust its red, green, and blue channels with a warmth slider.
A QUICK WALKTHROUGH
How to use this tool
- Enter a valid six-digit HEX color.
- Move the slider toward cooler or warmer.
- Copy the five resulting HEX shades.
RGB approximation
Warmth shifts red by 0.4 × amount, green by 0.1 × amount, and blue by −0.4 × amount in sRGB channel values. This is a visual approximation, not a physical color-temperature or white-balance model.
Five shades
The adjusted color is shown with darker 40%, darker 20%, base, lighter 20%, and lighter 40% blends. Output is HEX.
GOOD TO KNOW
Common questions
Does this edit a photo?
No. It adjusts one HEX color and creates a five-shade palette; it does not edit images or photos.
Which color space is used?
The calculation uses direct 8-bit sRGB channel arithmetic, so results are approximate.
Is my color uploaded?
No. All color math runs locally in your browser.
