Aspect translations

Dutch signalling system

sometimes there is also a number board. The number multiplied by 10 is the speed in km/h for the train

Aspect Translation
green green
white green with flashing number or flashing yellow with stable number in numberboard ; might be a hardware solution
red red
yellow yellow

remark: the color white is not used. A flashing signal could be used in some circumstances but in modelrailroad in my opinion not necassary. But:

flashing green : allowed to pass with the velocity number multiplied by 10 next block is free

flashing number and aspect yellow : allowed to pass with the velocity number multiplied by 10 keep braking the next signals aspect could be red.
