Grayscale Black & White Colors – High Contrast Theme & Skin

Remove all colors from web pages, convert them to black and white colour. All high contrast themes & skins are included.

The extension was removed! You can find alternative extension at Chrome Web Store, offered by Lunar Reader – Dark Theme & Night Shift Mode.

Change or invert the color scheme to make webpages easier to read. Turn on/off negative effect (high contrast) for all webpages on the same domain at once!

Change the color theme of any webpage in one click. Color setting is saved and loaded automatically on every domain.

“Grayscale Black & White – High Contrast Theme” lets you browse the web with your choice of several high-contrast color filters designed to make it easier to read text.

When you install this extension, all pages are “inverted”, so black becomes white and white becomes black. Press the “browser action” icon in the toolbar to toggle it on and off, or customize your settings on a per-site basis. Use a convenient keyboard shortcut to quickly change your settings while you browse.

Other extensions try to change the default colors, but this ends up breaking many popular websites. Only this extension applies filters to your page that invert almost everything – the only exception is photos, which are left alone.

Also note that the Chrome web store and other built-in pages like the New Tab page and Settings pages are unaffected – extensions like this one are not allowed to modify them, by design.
