High Contrast 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.

Risk impact

High Contrast requires a number of risky permissions that can potentially harm your browser and steal your data. Exercise caution when installing this extension. Review carefully before installing. We recommend that you only install High Contrast if you trust the publisher.

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

High Contrast has earned a good reputation and can be trusted.

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension, especially ones with higher risk impact and/or higher risk likelihood.
