Cosmic Veils are visual barriers at Juke Rooms and beneath most structural arches. Heroes can move through them. One face appears gray and the other has a rainbow sheen, giving the barrier asymmetric visibility.
From the gray side, the view loses color and enemy heroes and player 
abilities on the opposite side are hidden. Some visual effects remain visible, but most player-created objects cannot be seen through it. The rainbow side permits a view of players on the other side. Players can use this asymmetry to approach unseen or break pursuit.
Interactions
Veil Walker is an item designed around using veils.- The gray side breaks line of sight for
Billy’s 
Chain Gang, 
Lash’s 
Death Slam and 
McGinnis’s Mini Turrets. - The rainbow side also breaks Death Slam’s line of sight, but not the other two abilities’ line of sight.
The rainbow effect is based on thin-film interference, the optical phenomenon that produces colors in soap films and oil films.
