Image & ArtFree

ColorBlind Check simulates how digital designs, charts, and UI elements appear to people with protanopia, deuteranopia, tritanopia, and other forms of color vision deficiency, highlighting elements that become indistinguishable and suggesting alternative color choices that maintain differentiation for all viewers. The tool goes beyond simple filter overlays by analyzing whether the design's informational content is preserved or lost under each deficiency type. UI designers and data visualization teams use it to ensure their work is accessible to the estimated 8 percent of men and 0.5 percent of women with color vision deficiencies.
