Israeli Sea-Green submarine

I recently saw a picture of a Dolphin class submarine Israel imported from Germany painted a rather startling green. I inquired of a bubble-head if he knew why and one of his commentators guessed as better camouflage in the shallow Med. Then I saw this posting which refers to the "bright sea-green camouflage paint". I guess that settles it, thus proving that if you want a quick military answer go to a milblogger. I still think they ordered the paint job from the Volkswagen plant when they bought the sub.
