I can't comment on Blood Leopard as I'm anime-only and don't have enough information.
Though it's been mentioned before and she may just have neglected to put skill points in her ranged ability.
EDIT: Okay forget what I said, Cyan is blue+green. However, the nature of Cyan Pile's abilities and his appearance in color as well as how his color is described it would appear that it was simply a mistake of the author believing that Cyan is blue+purple.
EDIT2: Okay wtf is going on apparently the does know that Cyan is between blue and green but it's way to close to blue I'd call that Cerullean.
Still doesn't make sense as long as he doesn't have some purple in him, so I give up I don't know what's going on.
