Color Vision Labs
Free color blindness tests + a live color-assist camera
Free, science-based color vision tests that run in your browser: a 2-minute adaptive screening (type + severity), Ishihara, D-15, FM-100 and more — plates are generated fresh every run, so answers can't be memorized. New: a live camera filter (daltonization) that re-maps the colors you confuse into ones you can tell apart — processed entirely on your device. No sign-up, nothing uploaded, honest about what a screen can and cannot measure.
Hi Product Hunt! 👋
I built Color Vision Labs because most online color blindness tests have two problems: the plates are static images you can memorize (a real issue if you're retaking a screening), and they overpromise what an uncalibrated screen can measure.
So everything here is generated fresh on every run — the dot patterns and hidden figures are never the same twice. The adaptive test estimates your type (protan/deutan/tritan) and severity in about 2 minutes, and there's a full set of classics too: Ishihara, HRR, Farnsworth D-15, FM-100 hue, even an anomaloscope demo that's honest about why a screen can't do a real Rayleigh match.
The newest part is the Color Blind Filter: point your phone camera at anything and a WebGL daltonization filter re-maps the colors you confuse into ones you can tell apart — live. If you've taken the test on the same device, the filter tunes itself to your result automatically. Everything runs on-device: no uploads, no accounts.
I'd love feedback, especially from color blind users — does the filter actually help in daily situations (ripe fruit, status LEDs, charts)? What should I build next?
