Colors for All - Helping the Color Blind with a Free App

Color Blind Pal is a free app for iOS and Android that helps people who are color blind see the colors around them. It also lets people with normal vision see what it's like to be color blind.

Color Blind Pal has three basic modes. The first is color inspector, in which it delivers to its user descriptive information about the particular color, including the hue, saturation and value (or lightness) of the image that the user has captured on his or her device’s screen. The second is a mode that corrects for color blindness, in which a filter running at the bottom of the screen shifts colors so the user can distinguish colors better and more accurately. And the third is a simulation experience, or the “empathy mode,” in which the user can see the world as a color blind person would.
