Which Chess Set looks the best?

In this post I have 3 images. I want opinions on which background looks best in combination with the chess pieces.

The first option is a standard black and white chessboard background. It works because the pieces are still visible because whoever designed the Merida chess set made the black pieces not completely black but just a very dark gray.

The second option is what I call C0-40 based on the hex codes of the shades of gray I used.

The third option is called AA-55 based on the hex codes.

I can use any colors for the checkerboard pattern but these 3 were chosen for people with colorblindness so everything can be seen. People have different eyes and using red and blue for example would not be visible to everyone nor would it be traditional for the game of chess.

So please leave your comments on which one you like best!
