Horizon color when translucent

So in SkySafari 6 the ground in the "Translucent Area" option of the Horizon settings was green. This made sense to me as it represented the earth. It also was a very different color than the sky. In SS7, that setting makes the ground a deep purple. This is less intuitive as a color scheme and because it isn't different enough from the regular sky color, it can be disorienting, especially when zoomed in on a object with a small field of view. Its easy to get turned around and not realize whether you're currently looking above or below the horizon. I recommend changing this back to green or giving folks a color wheel to customize the view setting.
