Eyes certainly differ, and color acuities differ, 
and there are cultural differences in color 
boundaries and color terms: but still all human 
cultures agree to a remarkable extent on what are 
the 'most typical' or archetypical colors. The 
bright red, blue and yellow that we all know, and 
use to indicate fire engines and school buses and 
police signals, are also recognized as color 
prototypes even by people whose culture has no 
word for our 'yellow'. A bright mid-green is also 
seen as a typical color by almost all cultures. 
On the other hand, only Isaac Newton seems to 
have been able to distinguish purple from indigo.    (02)
