Bob, the reason for the orange / yellow color cast is due to the 
scattering of light by the atmosphere. When the moon is near the 
horizon, the moonlight must pass through much more atmosphere than when 
the moon is directly overhead. By the time the moonlight reaches your 
eyes, the blue, green, and purple pieces of visible light have been 
scattered away by air molecules. That's why you only see yellow, orange, 
or red.
You can also see it orange sometimes even when it is directly overhead, 
but this is due to the pollution in the air.
