Symbols associated to pieces appear to be wrong color

[mwpb]

Firstly, thanks for making this library available. I think all of the symbols associated to the chess pieces have the opposite color to the color intended. For instance on line 42 of the following file:

https://github.com/LordDarkula/chess_py/blob/master/chess_py/pieces/rook.py

we have

def _symbols(self):
        return {color.white: "♜", color.black: "♖"}

which is surely not as intended? Or am I missing something?
