We were looking around for functions to get the most used colors from an image, we will be using this when we follow up our child theme creators for the twenty eleven theme, which will be released shortly.
We spent quite a while looking around the internet for some php code to find the most common colors from an image, there was code for two different libraries the Imagick and GD2, as we test with XAMPP we soon found that by default Imagick was not installed.
