Property Value

The sky color opposite to the sun is created by interpolating the BackColor and the GroundColor. If this value is 0.5, the average color of the gradient (= average of BackColor and GroundColor) is in the middle. If this value is less than 0.5, then the average color is shifted up to the horizon. If this value is greater than 0.5, then the average color is shifted down to the ground.
