Color Maps

There are three Colormap groups, and each contains controls to set the coloring of the glow effect for a particualr direction.
The Preset pop-up offers both color set presets and a choice of using one-color, three color gradient, or five color gradient as shown:
One Color - With this setting one single color can be picked and the map is made up of a single color.
3-Color Gradient - With this setting three colors can be chosen: Highlights, Midtones and Shadows.
5-Color Gradient - With this setting, all five colors can be used: Highlights, Mid High, Midtones, Mid Low, and Shadows.
The following image shows three different settings for the preset menu.

One-Color | 3-Color Gradient | 5-Color Gradient
