Color ID (Color Identify) can tell you the name and content of any color with a tap. Take or choose a picture and tap to find the color at any point. Or just point the camera to see the name of the color at the center.
See data about the selected color, including the probability of each name, with the info button. Experiment with sample images including color-blind simulations. Color ID is ideal for color blind people struggling to identify colors. With voiceover support, it can also be used by blind or otherwise visually-impaired users.
Even color-normal people can use Color ID to settle disputes (the dress is brown and blue) and quench curiosity.
