Why Use a Color Blindness Simulator?

Approximately 1 in 12 men and 1 in 200 women have some form of color vision deficiency (CVD). Designing without considering these users can lead to inaccessible interfaces, where important information conveyed by color is lost. This simulator is a crucial accessibility tool for designers, developers, and artists.

By uploading an image of your website, app, or artwork, you can instantly see how it would appear to someone with a common form of color blindness. This allows you to check for issues like:

Text or links that rely solely on color for differentiation.
Important states in charts or graphs that become indistinguishable.
Buttons or calls-to-action that blend into the background.

Ensuring your design is accessible not only helps users with CVD but often leads to stronger, more robust designs for everyone.
