... can you reproduce any colour by mixing yellow, red and blue?Regards.
Kind of. Here is an 8 part article I wrote back in 2003 about Goethe's theory, colorblindness, and the physiological perception of color (please excuse the wayback links, but that's all I got):
1 - White is Green
2 - Receptors
3 - Color Spaces
4 - Brightness Matching
5 - Color Mixing
6 - Opponent Colors
7 - History
8 - Goethe's Prism
