You do remember the Scotland National Football team has worn Primrose and Pink shirts periodically throughout their history.
This as a nod to Lord Rosebery, a major investor in Hearts FC in the very late C19. The shirts were worn up through the 1950's and then once in the 1990's and haven't seen a return since. I have a reproduction of the 1909 shirt in the "Rosebery Colours" - hoops.
