When I was in high school back in the 70s a biology teacher explained  
that Newton squeezed indigo into the rainbow because of his  
numerological obsessions. And we got to look at the Ishihara colour  
test cards and discovered one of our classmates was colour blind.

Bit of a shock for him, but it's OK he's a consultant surgeon now.

Not a pilot Maru.
