👁️ Color Blindness Simulator

About color vision deficiencies:
Protanopia (~1.3% of males) — no red cones. Reds appear dark/brownish.
Deuteranopia (~1.2% of males) — no green cones. Greens shift toward brown/yellow.
Tritanopia (~0.001%) — no blue cones. Blues appear greenish, yellows pinkish.
Achromatopsia (~0.003%) — total color blindness, seeing only grayscale.
Anomalous types (protanomaly, deuteranomaly, tritanomaly) are partial versions.
