How bout Coke red with a big Sprite boy on it.. and large Coke bottles...
ha ha
I would think the 76 would be neat and the colors in those decals could be cool to use.. looks like some dark blue and oranges.. and those decals on it currently would look great on it.. I'm not familiar with 76 but I think that would keep the machine unique just like it is now!..
I wouldn't go a regular brand.. keep it off brand.. and use that brands colors..
