[visionlist] [cvnet] Robert Musil and the Color Wheel

[Manuel Spitschan]

Rob,

See Fig. 2 in Kuehni's article:

Kuehni, R. G. (2010). A brief history of disk color mixture. Color Research & Application, 35, 110–121. doi:10.1002/col.20566 

To see the original drawing, you'd have to consult his correspondence with Goethe.

Manuel
