Foil Wrapped Truffles

A local vendor is now making chocolate truffles. You can see their display case well before arriving at the stand. Children spot it immediately and dash off to stare at the rainbow-colored domes. Some colors are obvious; pistachio should be green and royal blue is perfect for the blueberry-filled ones. How did they assign the rest of the colors? They were too busy for me to ask silly questions. I chose a lavender-flavored truffle and left them to deal with the rest of the waiting chocoholics.
