Chewbacca’s bowcaster is firing red projectiles in Episode VII. As far as I can remember from movies, shows and games bowcasters only fire green projectiles.

Why does Chewbacca’s bowcaster fire red projectiles in The Force Awakens? Is there more information about this bowcaster? Have there been others that I did not notice?
