They got most of it right, but it is not enough

Repeat after me; Red, Orange, Yellow, Green, Blue, Indigo, Violet. If it was Good Enough for Sir Issac Newton is should be good enough for me.

And what are those colours? A rainbow. So, why can't  Rainbow Painting get the colours right? At least the firm didn't make the mistake of putting green and red next to one another. But the spectrum of visible light goes red to violet. (Hence infra red and ultra violet.)

Just another petty rant from a someone who gets pedantic about basic science.
