About this tool

Pick how many colours you need (3-12) and an optional base hue. The tool samples evenly spaced hues in OKLCH, clamps each into displayable sRGB, then shows the original plus deuteranopia / protanopia / tritanopia simulations side by side. The minimum pairwise ΔE under each simulation is reported so you can spot collisions.
