I found interesting the identification of different clusters. Now do some learning over the clusters. Letter cut out from colored shape seems to be the most prominent feature, and the most boring one. But some of the shapes (without cut-outs) are rather interesting.

The problem is, a logo should be as unique as possible, so mechanical derivatives aren't convincing
