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)
