Adding Color to Terrains
Color in the Terrain Editor is used as a visual aid to help you see the relationship between color values and altitude.
This color only exists in the Terrain Editor and is not applied to the terrain object.
When you apply color in the editor, it maps a Gradient to the altitudes in your Terrain Canvas. For example, if you apply a gradient from blue to yellow, blue might represent the lowest altitude while yellow may represent the highest. Which colors are mapped to which altitudes is left completely up to you.
Gradients can be extremely useful when you're filtering terrains, as they emphasize the differences between gray levels.
