ColorAid: Color Blind Helper

The color blind helper that does it all: name colors, find them, compare them and test your color vision. Free, private and offline.

ColorAid is made for people with color blindness (color vision deficiency): red-green (protan, deutan) and blue-yellow (tritan). Point your camera at anything and get a clear answer in a second.

IDENTIFY ANY COLOR
• Tap the picture and get a precise name like "Navy", "Olive green" or "Burgundy", plus the main color family (red, green, blue…).
• Simple names mode: only the main color, for quick and certain answers.
• Hear it: ColorAid reads the color out loud, on tap or automatically when the color changes.
• Zoom 2× and 4× for small things like wires, LEDs, labels and threads.
• HEX and RGB codes, copy in one tap, save your favorite colors.
• Flashlight for dark places, freeze the picture, or open a photo from your gallery.

FIND A COLOR
Choose red, orange, yellow, green, blue, purple, pink or brown: everything in that color stays bright and the rest turns gray, or gets highlighted with stripes. ColorAid also tells you how much of the picture is that color. Perfect for ripe fruit and meat, maps and charts, cables, charging lights, clothes and games.

COMPARE TWO COLORS
Do these socks match? Is this shirt the same color as the pants? Take color A and color B and ColorAid tells you if they are identical, similar or different, whether they go well together, and how readable text would be on them.

COLOR VISION TEST
A quick test with 11 dot plates shows if you may have difficulty with red, green or blue, and how strong it is. With one tap ColorAid turns on the best filter for you at the right strength.

FILTERS FOR YOUR EYES
• Help filters for red-blind, green-blind and blue-blind vision, with adjustable strength.
• High contrast and grayscale.
• Simulation modes: show family, friends, teachers and designers how you see the world.

BUILT FOR ACCESSIBILITY
Large buttons, high-contrast text, a large text option, vibration feedback and light and dark themes. Six languages: English, Italiano, Español, Français, Deutsch and العربية.

PRIVATE BY DESIGN
Everything works on your phone. Camera images are processed live and never saved, uploaded or shared. No account, no tracking.

Good to know: ColorAid is a helpful tool, not a medical device. The vision test is not a diagnosis: see an eye doctor for a proper check. Colors can look slightly different depending on your camera and lighting.
