CRDL has a bird motif, so one would assume the non-color motif isn't limited to any specific thing. A team just has to have the same type of motif (fairytales, historical or religous figures, species of a type of animal, novels, flowers, numbers, constellations, etc), and standalone characters can, assumably, have a motif of anything they want. The four  Faunus shown also seem to have a bit of an animal motif in regards to their respective animals (Blake being cold at first, but then warming up over time, Velvet being, from the very little we've seen, sweet, innocent, and preyed on, Sun being...well, a banana-loving trickster, though he does get excused slightly for being based off of the Monkey King, and Adam, if he is indeed a bull Faunus, being unwilling to listen to other peoples' views, which could be called "being bullheaded").

But I don't think anyone will really blame you for not wanting to go into that. The color motif can be hard enough as-is, and the motifs are more for aesthetic porpoises than story porpoises.
