Looking at your valve, I would say the first part of the valve receives water from the house spigot then once energized, sends waer to the filter. From the filter water would enter the second part of the valve and flow out of whichever side of that valve is energized, either icemaker or water dispenser.
Based upon your statement, I would imagine the brown is for the valve leading to the filter. It should energize every time the yellow (water) and green (icemaker) is energized.
