In case you were also looking for a blue PCI NIC and 1394 card, here are two model numbers from my own stash.  I can't speak to the quality/reliability of these cards, only that they are blue!
Netgear FA310TX Rev 2.  However it's only 10/100 not gigabit.  And honestly it's slightly more "teal" than it is blue, but it's closer IRL than in the photos.
