A farmer kept his rabbits in three different-colored hutches, which were lined up in a row. One morning (when none of the rabbits were pregnant) the green hutch had twice as many rabbits as the yellow hutch. The farmer took 5 rabbits out of the left-most hutch and donated them to the local school. He then moved half of the remaining rabbits in the leftmost hutch to the red hutch.
What color was the leftmost hutch?
