This free online color blind test screens for color vision deficiency (color blindness) and estimates its type (protan, deutan, or tritan) and severity. It takes about two minutes, needs no sign-up, and stores no personal data. Screening is reliable on a normal screen; the type and severity are best read as estimates, since an uncalibrated display can't fully match a clinical exam.
What your result tells you
Do you have a deficiency? This is the part to trust. On any normal screen, the yes-or-no screening holds up about as well as a clinic's first-pass test.
Which type is it? Read this as a strong hint, not a label — red-weak (protan), green-weak (deutan), or blue-yellow (tritan). Mild red and green are the easiest to mix up.
How strong is it? You get a relative score, handy for comparing one attempt with the next. It isn't a calibrated clinical grade.
Need it for something official? For a driving licence, a job, or a medical question, have it confirmed by an eye-care professional (an anomaloscope or CAD test).
