Iridescence Gradient Map Set

Gradient map set for applying iridescent colours for things like soap bubbles, pearls or oil spills.
Works best with soft brushes with colour mixing setting applied and painting under the gradient map using black and white.
To import the gradient set, open the settings for a gradient map layer, select the wrench icon and select "Add gradient set." The set should appear under "downloaded materials."
Setting the Gradient Map layer to "soft light" and "pin light" blending modes produces nice effects.
