Golden Eagle Update - Color Receipes

I toned down the right eye on the left pic and I think that is an improvement - this is meant to be one side in light and one going into shadow.  Does it need more toning down?  Also should I put some more semblance of feather work into the shadow side so it doesn't look like such a distinct line of stopping?

For - Mix - Why

Bright green – Lemon Yellow w/ Phthalo Blue – neither have a trace of red

Dull Green – Lemon Yellow w Ultramarine Blue - Ultramarine has purplish cast due to traces of red so red dulls green

Duller Green – Cad Yellow Med with Ultramarine Blue – has traces of red in it

Dullest Green – Cad Yellow Deep w/Ultramarine Blue – large amount of red in these colors

Bright Orange - Cad Red/Grumbacher Red w/ Cad Yellow Lt

Dull Orange – Cad Yellow Med and Permanent Rose or Quinacridone Red – red needs to have a trace of blue in it

Duller Orange – Cad Yellow Deep and Quinacridone Red blues neutralize the orange-greens

Dullest Orange – for a really earthy orange Yellow Ochre and Cad Red Deep

Intense Violets – don't use anything that has yellow, use bluish red with reddish blue – avoid Phthalo blues, Ceruleans, Cobalts and most Cadmium reds.
