The charms are the H and the other thing (is it an eye or an O?) on top of the palette. You can apparently pick and customize those and click them onto your palette
Not the shades. After their last customizable quad that sold like hot cakes and had people all over the comments beg for more custom options, they decided that yes, we can custom palettes, but only the outside!
This is the only available shade option right now and not their holiday release yet.
