Example input
#ff6600 deuteranopiaThe browser workflow processes #ff6600 deuteranopia locally and produces a result you can inspect before export.
Deuteranopia Simulator
liveSimulate deuteranopia and other common color-vision deficiencies. TypeKitty's deuteranopia simulator runs locally in your browser, so you can review colors and images through several color-blindness models.

A simulation is an accessibility aid, not a diagnosis
Deuteranopia changes sensitivity to green light, while protanopia and tritanopia affect different parts of color perception. Matrix-based previews are useful for finding risky combinations, but individual vision and display conditions vary. Treat the result as a design review signal.
Do not rely on color alone
After reviewing a simulated color or image, check whether labels, shapes, patterns, and contrast still communicate the same meaning. Error states, charts, and status indicators should remain understandable even when two colors become difficult to distinguish.
