the dealer where I got my PA only had one on the floor and it was yellow. The dealer told me they had 2 others available in the other colors, but in another store 5 hours away. I had made up my mind to have one "today" (I was driving 200 miles to get one) so color was not much on my mind. However; in retrospect, yellow was probably the best color as the boat is low in the water anyway, and the yellow makes it more visible, at least in my mind, and my mind is more comfortable with the thought I won't get run over by some nutcase in a high powered boat...you know what I mean? Pick yellow!
Magic eraser took care of that. I usually splash some water on any blood, coffee etc when it happens and don't worry about it.
