ColorSight gives you the power to identify any color in the world around you — instantly, accurately, and entirely on your device. Designed from the ground up for people with color vision deficiency, ColorSight doesn't just name colors — it explains what those colors mean for the way you specifically see the world. No internet required. No subscriptions. No barriers. LIVE CAMERA IDENTIFICATION Point your camera at any object and get an instant color name, hex value, and RGB breakdown in real time. Tap to freeze on a reading, long-press to refocus. Pinch to zoom in for precise sampling of small or distant objects. Toggle the flashlight for low-light environments. PHOTO EYEDROPPER Import any photo from your library and drag a magnifying loupe across the image to sample exact colors pixel by pixel. Perfect for identifying colors in photos, documents, clothing, or designs. BUILT FOR YOUR VISION PROFILE ColorSight supports five color vision profiles — Normal Vision, Deuteranopia, Protanopia, Tritanopia, and Achromatopsia. Select yours in Settings and ColorSight adapts throughout the app: Contextual notes explain what each identified color likely looks like with your specific profile Confusion warnings flag colors commonly mixed up under your profile — such as red and green for deuteranopia — shown when you lock in on a color and in your saved history. Toggle them off in Settings if you prefer a cleaner view. Achromatopsia mode leads with brightness labels ("Medium Dark", "Light") instead of color names, since brightness is the actionable information when you see in grayscale CVD-adapted descriptions use plain language about what your profile actually perceives HUE ISOLATION MODE A real-time camera filter that keeps one chosen color family visible and turns everything else to grayscale. Select Red, Blue, Green, or any other hue family and instantly see which objects in a scene match — making a target color pop out from a cluttered background. HIGH CONTRAST MODE Boost brightness and contrast in the camera view for better visibility in low-light environments — without affecting the actual sampled color values. Your readings stay accurate even when the image is enhanced. STABLE, ACCURATE READINGS Region sampling mode averages a small area of pixels instead of a single point, giving more stable and consistent readings on textured surfaces like clothing, fabric, and patterned objects. Combined with pinch-to-zoom, you can identify colors precisely without needing to get close. COLOR HISTORY Every color you lock in is saved automatically to your personal library. Copy the hex value, share a swatch, or revisit past colors anytime. ACCESSIBILITY FIRST Full VoiceOver support with color name announcements on every identified color Haptic feedback encoding brightness as pulse intensity Flashlight toggle for low-light shooting Full Dynamic Type support — layouts adapt rather than clip at large text sizes COMPLETELY PRIVATE All color identification happens on your device using a bundled database of over 1,600 named colors. Nothing is sent to the cloud. No account required. ColorSight is free, forever.

Verdict
The clearest difference is rating: ColorSight at 5.0 against Scrolla's 4.3. ColorSight also leads on in-app purchases (none vs 3) and review sentiment (100% vs 87%). Scrolla's advantage is update cadence (every 3 days vs every 5 weeks) and ratings volume (15 vs 3). On price, ads and device support there is nothing between them.

ColorSight holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Scrolla has 15 ratings behind it against 3, so its average is the more settled of the two.

ColorSight ships an update every 5 weeks, Scrolla every 3 days. The most recent releases landed on October 24, 2026 and October 29, 2026 respectively.
