Color Blindness Camera

Ever tried to explain which colors you can’t tell apart — and gotten a blank look? Color Blindness Camera let you show people instead. Point the camera at anything and your phone shows people what you see. Or select an image from your photo library. SIMULATE THE THREE MOST COMMON TYPES OF COLOR BLINDNESS • Protanomaly (red-weak) • Deuteranomaly (green-weak) • Tritanomaly (blue–yellow) A severity slider runs from normal vision all the way to full dichromacy, so you can match the comparison to your own experience. ZOOM WITH EVERY LENS The Lens button switches between your iPhone’s cameras the way the Camera app does — ultra wide, main, telephoto — and both panes zoom together. WORKS WITH PHOTOS TOO Pick any photo, then pan and pinch-zoom both panes in sync to zero in on the colors you want to compare. CAPTURE, SAVE, SHARE Tap the shutter and the comparison becomes a side-by-side card. Save it straight to your photos or send it on — a simple way to show friends, family, designers, or teachers what you mean. PRIVATE BY DESIGN Everything happens on your device. No account, no analytics, no networking. The app only ever sees the single photo you pick, never your library, and saving uses add-only access: it can add a comparison to your photos but cannot read what’s already there. The simulation uses the physiologically-based model of Machado, Oliveira & Fernandes (2009). It is an educational approximation of color vision deficiency; everyone’s vision differs, and Color Blindness Camera is not a medical or diagnostic tool.
