With Arcus - 7 Color Pattern Overrides, color-blind users can have a better browsing experience by ensuring that the colors of common links are distinguishable. The extension implements a seven-color palette specifically designed for color-blindness, making it easier for users with color vision deficiencies to navigate websites.

It is worth noting that the extension does not collect any data. Its sole purpose is to layer over a website's CSS for links, without compromising user privacy.
