Color Maps

There are three Colormap groups, and each contains controls to set the coloring of the glow effect for a particular direction.
The Preset pop-up offers both color set presets and a choice of using one-color, three-color, or five-color gradients 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

The 3-Color Gradient presets offer greater color diversity. When one of the presets is selected, the three colors are updated (Highlights, Midtones and Shadows). The colors can be tweaked to your taste.

Fire | Mars
Chemistry | Deepsea
Electric | Spirit
Aura | Heaven
Romance | Magic
USA | Rastafari

After these follow the 5-Color Gradient presets. When one of the presets is selected, the five colors are updated and the pop-up menu reflects the name until one of the colors is changed.

Enlightment | Radioaktiv
