If both players choose the same dinosaur, player 2's combatant will be an alternate color from player 1. Player 1 colors consist of the primary colors from the main game. Among player 2's colors are red for Allosaurus, light green for Compsognathus, orange-brown for Oviraptor, gray for Triceratops, black for Tyrannosaurus, and blue for Velociraptor.
