Color Temperature Adjuster
Warm up or cool down a color without opening a design app.
Warm or cool a color in seconds
Sometimes a color is right in hue but wrong in feel — a touch too cold for a cozy brand, or too warm for a clean tech look. This adjuster shifts a color warmer or cooler without opening a design app, so you can fine-tune the temperature and keep the character.
Small temperature shifts have a big effect on mood, and doing it with a slider lets you compare before and after directly. Nudge the value until the color feels right and copy the adjusted hex.
Warm and cool
Shifting toward amber warms a color and shifting toward blue cools it, without changing which color it fundamentally is. The adjustment runs locally with nothing uploaded.
