FWIW - couple more aspects in my neck of the woods: Lunar, Flashing Yellow and BlueRed, Green and Amber for 3 aspect 4 aspect are Red, Double Amber and Green, Red and Green for 2 Aspect, there's no other colour combination you realistically can have on a RR, unless you build your own, in which case there's no limit as to what colour combination you can have.
Lunar - for movements into un-bonded siding ( no detection )
Flashing Yellow - between Green and Yellow - more or less restricted - slow down next one is Yellow
Blue - used in fueling facilities when fueling; well that is BNSF, unknown if others use it.
