OPAL is part of our colorshift line. Its the opposite of our Aurora. Dichroic films are used to interfere light and change colors from different angles, this gives an almost Iridescent effect when walking around this film. This film can change colors similar to our AURORA film but has more blues, the shifting is from Blue/Turquoise/Green/Purple.
