This is something I did 20+ years ago. The picture is a scan of an old Polaroid picture, so the quality is not very good. The sign was an entry for a contest to win a full size arcade Pac Man machine. I came in 3rd overall. I drew the graphics to full size by hand. The sign was 4 ft. x 8 ft. overall. Anything white is standard Voltarc 6500 Snow White. The Pac-Man is clear bright yellow. The red ghost is old Corning coated ruby red. The pink ghost is standard blue filled with red gas. The blue ghost is standard blue with the normal argon/mercury fill. The tan ghost (the true color doesn't show in the picture) is an old Sylvania color called “flesh” (which would no doubt be exceedingly politically incorrect these days) and has not been made for decades. The blue in the eyes of the ghosts is coated cobalt blue, and the Pac-Man letters are coated noviol gold.
