Palettes

This was just a fun morning exercise. Let’s mix multiple images to make a palette of their principal colors using k-means. We’ll also use the totally awesome list-columns concept to put each image’s jpeg data into a data frame of lists that we can map to a function that turns the jpeg data into a list of palette colors in a new data frame. This more-or-less copies http://www.milanor.net/blog/build-color-palette-from-image-with-paletter/ with the added twist of using multiple images before creating the palette.
