When you say yellow and white are the only two colors, do you mean only two colors known? I can’t believe only two colors were ordered. Why would anyone pick white and yellow as the only colors (unless yellow and white have some sort of significance o the Sullivan family)

For 15 years not yellow and green were known of the Shriner chip. Finally 3 other colors showed up (actually only 1 or 2 are known of the other colors). Unless you have the order card, I bet there is at least a blue and red PJS out there.
