Colors in images

Question

I have an image and would like to take the predominant color of this image.

For example:

I have this image: http://etc.piktureplanet.com/wp-content/uploads/2014/11/Natural-Green-Wallpaper-for-Desktop-26.jpg

The predominant color is green, I would like to know how to identify this color, in different images, regardless of the predominant color.

This library can help: https://github.com/fleitz/ColorArt

With it you can extract information from the image, such as the background color.

Example of use:

UIImage *image = [UIImage imageNamed:@"test.jpg"];
SLColorArt *colorArt = [image colorArt];
primaryColorView.backgroundColor = colorArt.primaryColor;
backgroundColorView.backgroundColor = colorArt.backgroundColor;
