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
The bottom color is not "azul" or blue
, it's either violet
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.
