you could go with something related to his coloring like cerulean, cobalt, indie (indigo), or sapphire. if u want something stupid u could just say words until something funny fits him. electrical tape or something lol. here’s another list of things i think would be funny/ cute… weenie, poki, bibble, berry, mold, uranus, pluto, blue jeans
