Don,
Yea, that was the one drawback to the Novi I built last year. I'm telling you, light pearl green is not the color to have around here with all the "treed" backgrounds. Poof!, it's gone!
Recently, I took all the cans of custom mixed paints I have (about 40 pint cans and 5 or 6 quarts) and moved the paint over to canning jars. Besides now not having to worry about the darned cans rusting (don't you just love living in a high humidity environment?), I can see the color through the side. An upside to this is being able to put jars side by side to see how the colors will look together. Makes picking out trim colors a lot easier.
So I now have my paint scheme AND colors picked out.
Main color will be Alabaster Pearl White, trim will be Ford Redfire Pearl, A custom mix Orangy-Yellow pearl, GMC French Blue Pearlcoat(as sort of Burple color), BMW Custom Bronze Pearlcoat and a bit of Black Pearl. Should be interesting anyway. Certainly the jars standing next to each other look very good. Oh, and Hawai'ian shirt LOUD!
