Sunset Color

The Sunset Color symbol controls the colors displayed when any sun or moon rises or sets. Its usage is twofold: It can act as a modifier for any normal sun or moon; however, if found "dangling" at the end of the book (no sun or moon found after it), it will set the "default" sunset colors, for all suns or moons without their own sunset colors. Either way, it takes a Gradient modifier. (??? Does the global usage count as a Visual symbol?)
