Sorry,
Mistake in my previous Post.

Pale Feces: because there is an obstruction and conjugated bilirubin cant reach the intestinte to be converted to UBG to color the feces,

Dark Urine: Since there is an obstruction and the bile ducts are blocked, conjugated bilirubin overflows out of the liver into the blood and reaches the urine, to make it dark.
