Colorblindly is a free Chrome extension developed by oftheheadland. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This extension aims to help developers create websites that cater to colorblind users by allowing them to simulate the experience of browsing with colorblindness.

With Colorblindly, developers can choose from eight different settings to simulate various types of colorblindness. These settings include Blue Cone Monochromacy/Achromatomaly, Monochromacy/Achromatopsia, Green-Weak/Deuteranomaly, Green-Blind/Deuteranopia, Red-Weak/Protanomaly, Red-Blind/Protanopia, Blue-Weak/Tritanomaly, and Blue-Blind/Tritanopia.

It is important to note that this extension does not work on built-in Chrome domains such as the store page. To experience the simulation, users are encouraged to try it out on different websites. Colorblindly provides a valuable tool for developers to ensure their websites are accessible and user-friendly for colorblind individuals.
