two tone white? Frost or Polar White?

[frenchy51]

I'm getting ready to paint my 74 Blazer and am going with Nassau Blue and White two-tone. I just had the paint mixed and the white I got is FROST WHITE. I put a few drops of it on the lid and when it dried it looks a bit more off-white creamy than the more pure white I was expecting.....Did I order the wrong white? Should it have been POLAR White or? I like the 80's to 90's two tone white and I'm not sure of the code. Who thought picking a white would be so difficult. PS-I'm going Base/Clear. What is the correct name or code for GM white used in two-tone?? HELP!
