White ghosts - other players moving around in the same area as you
Blue ghosts - coop players
Red ghosts - from bloodstains, shows another player's last moments before they died. Handy to know if there's something dangerous nearby
Red with black ghosts - Black Phantoms, either npcs or other players. You'll know if its another player if you get a giant YOU ARE BEING INVADED BY MOONRUNES_5875_^_^ message on your screen, kind of hard to miss.
If you are ALIVE, you can be invaded by a black phantom, or touch the blue runes on the ground to summon a coop player who dropped their runes with the blue eye stone.
If you are DEAD, you can invade a live player with the black eye stone, or drop your coop rune with the blue eye stone to be summoned by a live player.
If you HELP a live player kill a boss in coop, or you KILL a live player as a black phantom, you revive.
If you suicide as a black phantom (either by walking off a cliff, or an environmental hazard), you lose a soul level - not if you die in pvp, just if you suicide, to discourage white alignment farming via black phantom suicide.
