How to use this tool
Add the colours you plan to use in a room or design. The tool simulates how each pair of colours appears under all 4 types of colour vision deficiency and checks if they remain visually distinct. A score of 80%+ means your palette is accessible to most people with CVD. For best results, aim for a contrast ratio of at least 3:1 between adjacent colours. Use the "Simulate View" buttons to see your palette through different eyes.
