Simulates colorblindness in your web browser.

Colorblindly – Experience Colorblindness in Browser

"Colorblindly" is a Chrome extension designed to help web developers understand the visual experiences of people with colorblindness. By simulating 8 types of color vision deficiencies, including various forms of monochromacy, and anomalies affecting red, green, and blue vision, it allows creators to view their websites as colorblind users do. This tool is vital for designing inclusive and accessible online content. Note: Colorblindly does not function on Chrome's own domains; use it on other websites for full effect.

It works perfectly and I was able to use it in my designing process on Substack.

The only page I'm unable to get this to work on so far is the chrome web store. If you are having difficulty, I would suggest clicking "manage extension" and changing site access to allow the extension to run "on click" instead of "on all sites"
