The target can be an existing file, or a new picture taken from your device camera.
Image Color Analyzer examines the colors used in your image, groups and sorts them from the most dominant to the least significant.
The report then gives you the breakdown of these shades, including their color names. You might see that the dominant color is "steel blue", there’s "khaki", some "cream", whatever it might be. Each color has a percentage figure representing its usage.
Your image will probably have too wide a palette range for this to be useful on its own, but the app also organizes similar shades into groups. If your image has five percent each of "ivory", "canary yellow" and "cream", for instance, Image Color Analyzer will show 15 percent usage for the "yellow" group.
While the color names bring some clarity, you’ll occasionally need the raw values as well, so it's good to see that the app provides RGB and hex codes for every shade.
If you need more power -- in particular, you'd like to save or do something more with this information -- the developer also produces a$0.99 Professional edition with a histogram, "export to Excel" feature and other sharing options.
