I hate black icons. I'm not racist or prejudice, but they just blend into the SpringBoard way to easily and look rather silly. Before you start "But, Apple's Clock icon is black!" ... I've never been a fan of the default Clock icon either... doesn't it just like it stands out compared to the brightly colored icons? Black on Black is stupid looking. Reminds me of somebody wearing black shirt, black pants, black shoes, black socks and black hat.... then having that person run on the side of the road at night.
