Alan - That vinyl name doesn't look right. Did you mean "Allanté" ?? I found this link:

Really nice stuff...
But Alan also brings up a very good point - For free, you can visit some local car dealers and find a color there on the lot that you like. It doesn't have to be a pure "Porsche" color, just a color that you like. Then, you'll have a modern paint code and can easily get water-borne paint (if that's what Greg's paint guy is using). You'll also be able to walk around the car and see how the sunlight or parking lot lights will affect it. My pearl white assumes different hues as you move around it and mercury-vapor parking lots lights make it glow slightly pink/orange. I also found that in the Glasurit catalog back in 1998, there were about 43 different shades of "Pearl White" ranging from blue and gray hues (Chrysler) to blue/pink (Audi/VW) to gold (Cadillac), depending on the choice of different car manufacturers. Grays are probably plentiful, too.
