I love the idea! :)</p>
<p>I wanted something like that, tough i had a slightly different approach.. i find the global average color usually producing a kinda washed down color (from what happens in the plasma mobile app startup screen)</p>
<p>For another project i needed something along the lines, and ended up using a variant of the k-means clustering technique, so you have averages of the colors grouped in clusters by frequency which can generate interesting palettes to play with (then is trivial to add a global average if really needed).<br />

<p>the first implementation is there (i want a way better api for it to be integrated in kirigami tough)<br />
