Using the transparent image (like everlong seatrt_empty) for my seatrt_off.
Transparent seat below
Re-worked your transparent/solid idea. Took my previous seatrt_off that was solid black, and deleted the center of the square, leaving a 3 pixel border solid. Made it with the border all of my previous bright shades. Makes for a pretty nice seatrt_on.
