Ostwald color system
The colorimetry is the science that studies colour and define their intensity. The basic colours are only three: yellow, red and blue.
Mixing to primary colours together, you obtain the three secondary colours. The secondary colours, orange, purple and green are the opposite of primary colours not being used in their creation so that green is complementary of red and cancels it, purple is complementary of yellow and cancels it and orange is complementary of blue and cancels it.



Through the star of Oswald we can observe the primary colours, the secondary colours and their capacity of neutralize.
