The student caps in Nordic countries are traditionally white (summer uniform) or black (winter uniform) but the colors of the bands, lining, tassels and cockades differ, depending on the school or the faculty. In German-speaking countries and in Poland, Estonia and Latvia, student caps come in a variety of colors, depending on the colors of the student organization or the school, and can be decorated with its zirkel (a monogram).
