ROY G BIV

Yesterday was "blue" day on our spectrum of posts for the week (I'm saving the easy colors for last); today is "O" for orange.  We stole the following from Wiki: 

Spectral coordinates
Wavelength	590–620 nm
Frequency	505–480 THz
Common connotations
warning, autumn, desire, fire, Halloween, Thanksgiving, prisoners, Orangism (Netherlands), Unionism (Ireland), Indian religions, engineering, determination, compassion, endurance, optimism

The color "orange" is named after the fruit. Who named the fruit? Oranges contain carotene and that gives the color - but that of course begs the question of why didn't they name oranges "carrots" (because the name was taken, silly).  I lost interest when I found out they add carotene to chicken feed to make for a brighter orange yolk.

Speaking of orange fruits......

Exit music....
