ofxColorFinder

ofxColorFinder is a openFrameworks addon that can give you the dominant color of any image. The following snippet shows how to use the addon:

ofImage image;
image.load("0.jpg");

ofColor dominantColor = ofxColorFinder::getColor(image);

You can also customize the algorithm so it favors colors you specify. This can be done by providing a callback to the ofxColorFinder::getColor() method. The following code favors dark colors:

ofImage image;
image.load("0.jpg");

ofColor dominantColor = ofxColorFinder::getColor(image, [](int r, int g, int b) {
	return 768-r-g-b+1; 
});
