Color Temperature Adjuster

How to Use Color Temperature Adjuster

1. Upload an image — click the drop box, drag a file in, or paste with Ctrl/⌘+V.
2. Drag the temperature slider from -100 (cool blue) to +100 (warm amber).
3. Watch the tone label switch between Cool, Neutral and Warm as you slide.
4. Choose the output format — PNG for a lossless result, JPG for a smaller file, WebP for the best mix.
5. Download the re-tinted image.

Warm vs. cool in practice

Warm (positive values) adds golden and amber tones, which flatters skin, food and golden-hour landscapes. Cool (negative values) pushes toward blue and cyan, which suits snow, night scenes and sleek tech products. Small values around ±15 give a natural correction; ±60 and beyond create a deliberate mood.

Fixing a color cast

Indoor shots under tungsten bulbs often look orange, so a cool shift brings them back to neutral. Photos taken in shade or on an overcast day lean blue, so a warm shift restores natural color. Adjust in small steps and compare against a known white area.
