Watch a page change color
One page, 17 color schemes and 9 animated backgrounds. Every frame is the real extension at work.
What it actually does
What works right after install
Everything runs on your device. The free version needs no account.
All 17, including the 6 vivid ones
Eyecare, high contrast, dark and vivid — pick what your eyes like.
Frosted glass and color blobs (vivid set)
The page background really blurs; the UI stays crisp.
Animated backgrounds (9 animations, starfield and meteors free)
Rain, snow, starfield, meteors, fireflies, bubbles, leaves, fireworks, grain. Starfield and meteors are free.
Dark themes (smart invert, invert overlay)
Dark mode for sites that never built one: smart invert and invert overlay.
Per-domain settings
Set one per domain once, and it sticks.
Nothing leaves your device
Colours are computed locally: no browsing history is uploaded, no page text is read.
17 built-in presets
Ready on install. Every shot is what the extension actually renders.

Animated backgrounds
Add a moving layer behind the page
Nine animations across seventeen presets — the same particles read as a starry night, autumn leaves or fireworks in the snow.
Starfield and meteors work right away. With "reduce motion" on, you get a still frame.

Common questions
Can I use Pro on several computers?
Yes. One license covers up to 3 devices. You can remove a device from your account page at any time.
What happens when my subscription ends?
The extension falls back to Free. Your presets and site overrides stay saved, so nothing is lost if you come back.
Install it and see for yourself
The free tier stays free. Upgrade only if you want glass and motion.
