Take a quick screening, then point your phone at anything — and watch a live simulation of what a colorblind person sees.
Just for fun — not a medical test. This is a casual screening and a perceptual simulation, not a clinical diagnosis. If you have real concerns about your vision, see an eye-care professional.
