Color Blindness Simulation Prompt Generator
Used by developers, writers, and creators worldwide.
A color blindness simulation prompt generator writes ready-to-use AI prompts for checking whether a color palette works for people with color vision deficiency. Around one in twelve men has some form of color blindness, so palettes that rely on red-versus-green contrast can fail a real share of users — but checking for this is easy to forget. This tool produces detailed prompts that ask an AI to review your colors against the common types of color blindness and suggest safer alternatives. Click generate, copy the prompt, and paste it alongside your palette into an AI assistant. It is ideal for designers, data-visualisation work, and anyone building accessible interfaces. A good accessibility prompt asks specifically about deuteranopia, protanopia, and tritanopia, flags risky pairs, and reminds you to add non-color cues. Use the AI review as a guide, then confirm your final design with a real color-blindness simulator.

FAQ
what does this tool produce
It produces a detailed text prompt you paste into an AI assistant alongside your palette. The prompt asks the AI to review your colors for color-blindness accessibility and suggest safer alternatives for any risky combinations.
why check for color blindness
Around one in twelve men and one in two hundred women has some color vision deficiency. Palettes that rely on red-versus-green contrast can fail these users entirely, so checking ensures your design communicates to as many people as possible.
is an AI review enough on its own
It is a helpful first pass, but not the final word. Confirm your design with a real color-blindness simulator, and always pair color with another cue — a label, icon, or pattern — so meaning never depends on color alone.
