FAQ

What scenarios is a Color Blind Simulator suitable for?

Suitable for web design, App UI design, poster color schemes, data visualization, and accessibility experience checking. Helps discover color indistinguishability issues early.

Can I preview how images and color schemes look under color weakness perspective?

Yes. The tool helps you simulate how images, color blocks, and color schemes appear under different color vision deficiencies, convenient for quick comparison before and after design.

Can it preview both red-green and blue-yellow color blindness?

Yes. Common color vision deficiency types can be viewed individually, making it easier to optimize visual accessibility for different user groups.

Can this tool replace real user testing?

It's very suitable for early self-checking and quick screening. However, for important projects, it's still recommended to combine real user feedback and complete accessibility evaluation.
