Newb; what are all these plugs for? :)

Hello :) I would like to know what all these ports are:
Blue = ??? (line-in, I believe, but such as what?)
Green = Speakers (at least I know that one :))
Pink = ???
Orange = ???
Gray = ???
White = ???
Yellow = ???

And also, I would like to rip music from a game, without having to unplug my speakers; how could I go about doing that?

Thanks!
