FAQ

Questions, answered.

Is LumenShade really free?+

Yes. No paywall, no trial. The extension is free now and forever.

Does LumenShade collect my browsing data?+

No. Everything runs locally in your browser. There's no telemetry, no analytics, and no account system.

Why not just use Chrome's built-in dark mode?+

Chrome's experimental dark mode flag is a global filter — it inverts colors crudely and breaks images. LumenShade rebuilds each page's palette intelligently.

Does it work on every site?+

It works on the vast majority of sites. Some heavily-styled web apps (Figma, Notion, etc.) already provide their own dark mode — for those, just disable LumenShade per-site with one click.

Will it slow down my browser?+

The content script is tiny (~18 KB) and runs once at page load plus debounced re-runs on DOM changes. You won't notice it.

Why OKLCH instead of HSL or LAB?+

OKLCH is perceptually uniform and was designed specifically for screen color manipulation. It produces results that look right to human eyes, not just mathematically correct.

Does it support Firefox?+

Not yet. Chromium first (Chrome, Edge, Brave, Arc, Opera). Firefox support is on the roadmap.
