On the Wabash Railroad, one of the aspects used for Diverging Clear was lunar white over green. Some of these unusual aspects survive to today's Norfolk Southern.
Pictured here is the westbound absolute signal at Flint, Indiana. The Diverging Clear is displayed to train 35Z, allowing him to leave the siding after a meet with 146.
When displaying its most restrictive indication (Stop), this signal displays dark over red.
