An toy set having at least one section which bears a color memory dye of an electron-supplying organic coloring compound, an electron accepting compound and an ester. The color memory dye assumes a first color below t1 ( DEG C.) and a second color above t2 ( DEG C.), wherein t2>t1, 0</=t1, t2</=50 DEG C. and 5</=t2-t1</=35. Both the first and second colors can be displayed between t1 and t2. For the purpose of determining the proper temperature range for a color characteristic, temperature-sensitive visual indicators are provided.
