Bauhaus Optical Mixer of Colours des. Ludwig Hirschfeld-Mack for Naef Spiele

Suitable for age 6 and above, this beautifully made toy shows how an optical colour mixture is produced when rotating the spinning top. Aspects of colour theory can be experienced with the interchangeable seven cardboard discs. The colour circles according to Goethe, Schopenhauer and Hölzel can be rotated and then compared with each other. Information describing the phenomenon can be found on the back of the discs.
