Why I built a tool to fix color cast online
A couple of years ago I shot an entire birthday party under those dreadful fluorescent lights. Every single photo came out with a sickly green cast, like everyone had just stepped out of a submarine movie. I spent hours in editing software adjusting sliders, and I just knew there had to be a faster way to fix color cast in photo online without installing anything.
That's exactly what this tool does. It uses a gray‑world auto white balance algorithm — it basically assumes the average pixel in your photo should be a neutral gray, then figures out how much each color channel needs to shift. It works surprisingly well for most everyday shots, especially indoor ones. And if it's not perfect, you've got the sliders to nudge things back.
I use this online color correction tool all the time now before posting anything. It's saved me from throwing away otherwise great memories just because the lighting was garbage. Give it a try — you might be surprised how easy it is to remove a yellow cast from a photo or tone down that aggressive blue from a snowy day.

Common questions about fixing color casts
What exactly is a color cast and why does it happen?
A color cast is when your photo has an unnatural tint — too yellow, too blue, too green. It happens because different light sources have different color temperatures. Your eyes adjust automatically, but cameras don't. Fluorescent lights are usually the worst offenders, making skin tones look sickly. This tool helps you fix color cast in photo online without any complex software.
How does auto white balance work?
The gray‑world algorithm assumes the average of all pixels in a well‑balanced photo should be a neutral gray. It calculates how much the red, green, and blue channels are off, then applies the inverse correction. It's not perfect for every photo — like a sunset you want to keep warm — but for most everyday shots it nails the color correction online.
Can I remove a yellow cast from my photo?
Absolutely. Yellow casts usually come from incandescent bulbs or shooting in the evening. Click the "Auto White Balance" button and the tool will push the temperature cooler to compensate. If it goes too blue, use the temperature slider to warm it back up just a touch.
What if auto white balance makes my photo look worse?
It happens — especially with photos that are intentionally warm (golden hour shots) or have a dominant color (fields of green grass). That's why I added the strength slider. Crank it down to 50% or 30% and you'll get a subtle fix without losing the original mood.
Will this work on old scanned photos?
Yep. I've used it on scans from the 90s that had yellowed over time. The online color correction tool brought back surprisingly natural skin tones. For severely faded photos, you might need to boost saturation a bit too.
Is my photo safe? Do you store anything?
Zero. Nothing. The entire photo color fixer runs in JavaScript inside your browser. I never see your images, I never store them, and there's no server involved. You could disconnect your internet and the tool would still work fine.
