Short-Lived TV Series for 100

[swestrup]

I'm trying to remember the name of a TV series from a few years ago. It was about a guy who woke up naked on an island, in the middle of a large burned area in the shape of a symbol. The symbol was also on his body. He couldn't remember anything from before that moment, but he woke up being a huge storehouse of knowledge. He can speak every human language, knows how the stock market will perform based on first principals, and so on.

He's also color blind, except for a few object/people that he can see in color. He spends his spare time helping the cops solve crimes.

Ring any bells?
