Neil, there is no violet and there is green. The Spanish explanation includes "verde" and "azul", green and blue (albeit two shades of blue).

Call it what they will, the top color is not "verde,"
green, it's
chartreuse, which is yellowish green, a tertiary color.
Green is secondary.
The bottom color is not "azul" or
blue, it's either
violet or
indigo.
Blue is primary, and the sky blue stands in place of blue, so you can't have two different colors and call them by the same name.

BoR Francis has a long history of involvement with Latin American youth groups, so he's quick to jump on the bandwagon.
Plus, this gives him a chance to appear friendly to Sodomite agendas, when these days he needs all the friends he can get.
