Red Stripe for iOS

The color differentiator.

Red Stripe helps people with a red-green color blindness distinguish various colors by adding a stripe pattern over reds and a dashed stripe pattern over greens. Use it to differentiate ambiguous colors on documents, signs and maps, or just to observe the colors around you.

Just open Red Stripe and direct the camera where you want. You’ll see the camera’s picture with superimposed stripes in real-time.

Continous stripes indicate red or a redish color such as purple. Dashed stripes idicate green or a greenish color such as turquoise. A color with a substential green component such as sky blue will also appear with dashed stripes.


Stripes are visible by default on greens and reds. But to better isolate certain colors on a picture you can toggle each stripe type.
