Cokin Polacolor filters come in three shades: Red, Blue and Yellow. These Polacolor filters allow you to take polarized pictures with a colorcast. When used alone, the Polacolor colors the entire image with its own hue as it is rotated.

If you combine a Polacolor with a Neutral Polarizer, you can vary the intensity by rotating the Neutral Polarizer. For example, depending on the relative rotation of the Polacolor Red filter and the Neutral Polarizer, the reflections become either a slight red tint or extreme red tint.
