When designating switch direction for non main lines - ie switches entering yards, are there other colors used or is the same green / red format used?
How do you do 3 way and 4 way switches? - switched direction green; everything else red? Does anybody use any other LED colors for yard switches (white, blue, yellow)? What's prototypical?

Although it may not be obvious why, 3-way and 4-way switches do not exist in the real world. Consequently, there is no prototypically correct color set, except to continue to use red and green only.
How does this really work? instead of cramming two or three sets of diverging rails on top of the through track, and on top of each other, they're actually stretched out in a row one after the other. The track gangs actually just lay out two or three independent standard switches sequentially in order to achieve two or three tracks diverging from the through path.
Why? Real-world yards, and all rail lines in general, do not have to be shoe-horned into a tiny little space as we have to do on our layouts. They can live with the extra linear distance that two or three standard switches in a row occupy when they're used to complete this kind of job.
No need for other colors in yards in the real world as a result -- just use red/green in each signal head or dwarf, applying one head or dwarf for each of the diverging paths/switches.
