1) I think blue is okay. Given the blood colors that exist in nature (blue, yellow, green and red), the resulting color of a chimera ant's blood should be brown, but I don't think brown would look gorey.

2) Mentally overpowered? I think he's alright. Killua remained cool and calm because he's confident of his skills and he knew right after he heard the voice in his head that he won't be able to defeat the enemy unless he develops a plan that'd work. And his knowledge of knowing how to play darts is supported by his training as an assassin. If you go back to those episodes where he kinda explains to Gon how boring he said it was to just stay in their Estate and train to become an assassin all day, you won't really think he's OP. Like Bisuke and Razor said, he's a real prodigy. He's able to do feats like that (catching the arrow fish by using electricity on his skin and arm) and that's been pretty much established way before earlier in the series that he's a brilliant strategist, and just like Gon, a monster in the making.
