Colorblinding

Developed by @LeonardoCardoso.

An extension for Google Chrome (and Chromium) that simulates the website as a color vision impaired person would see. So you, as a developer, can adjust the colors for their accessibility.

Options

  • Red-Blind / Protanopia
  • Green-Blind / Deuteranopia
  • Blue-Blind / Tritanopia
  • Red-Weak / Protanomaly
  • Green-Weak / Deuteranomaly
  • Blue-Weak / Tritanomaly
  • Monochromacy / Achromatopsia
  • Blue Cone Monochromacy

Installation

The latest release is always available on the Chrome Web Store accessing by this link Colorblinding.

Important

  • If the website already uses a filter in its css, the elements might change their original location when applying Colorblinding. To get them back, just select the option deactivate and refresh the page if it doesn't do it by itself.
  • Colorblinding works in all tabs and the filter is applied when the tab is fully loaded.
