Simulation uses the Machado, Oliveira & Fernandes (2009) matrices at full strength in linear RGB; the “-anomaly” types are the same matrices blended 60% toward normal vision, a common approximation. Contrast is the WCAG 2 ratio of the simulated colours: 4.5:1 for body text, 3:1 for large text and UI parts. Click any swatch to copy its simulated hex. Nothing leaves this page.
