I feel like only coloring half isn't telling the whole story. How about a lighter shade of reddish-brown, e.g. Zinnwaldite as the back? I don't like the idea of highlighting all four in green... can't tell the difference between winners and losers if all the same color-why color at all?. Alternatively, I like the idea of the top two (those who advance) in a light color. Perhaps we could have the top two in green and then bold the last match (e.g. if Sweden won their last match, their total in the W column would be bold).
