A Color Blindness Simulator shows how websites, images, and digital designs may appear to people with different color vision deficiencies. It helps designers and developers evaluate color-dependent content and visual elements.

Yes.

Yes. It can help evaluate how logos, graphics, brand colors, and other visual elements may appear under different color vision simulations.

The simulator provides a close approximation of different color vision deficiencies. Individual perception can vary, so simulation should support - not replace - broader accessibility evaluation and user testing.

No.

Yes.

The tool supports simulations for deuteranomaly, deuteranopia, protanomaly, protanopia, tritanomaly, tritanopia, achromatopsia, and the additional color vision option available within the simulator.

Yes. Enter a website URL or upload a supported GIF, JPG, JPEG, or PNG image to preview it using different color vision simulations.

No. The simulator can help reveal color dependent design issues, but it does not determine overall WCAG conformance. Additional accessibility testing, including color contrast evaluation, is required.

No. Accessible design should avoid using color alone to communicate important information. Labels, icons, patterns, shapes, or other visual cues can help make information easier to distinguish.

Color Blindness Simulator works across all major browsers such as Chrome, Firefox, Safari, and Edge, making it easy to test color blindness accessibility on various platforms.
