Re: yellow with no green

Pinguino, this looks like the sequence of colours typical of edge spectra, such as you see when a broad beam of light passes through a prism, or when you view a white band on a black background through a prism. On one side you go from violet to blue to blue-green to white as you add more and more of the longer wavelengths, while on the other you go from red to orange to yellow to white as you add more and more of the shorter wavelengths. The complete sequence if you see it is violet/blue/blue-green/white/yellow/orange/red.
