Part of the difficulty was not making the colors TOO bright. They're painted on stone, and making them too 'solid' would wash out some of the detail on the statue itself. I wanted to preserve the impression that this statue was stone, and not make it look like a piece of plastic.

I will say to me, that although the color in the picker is a bit greenish, it looks solidly yellow - though clearly with a green tint - to me. If you're using a flat screen, it may be that your particular monitor isn't set to represent colors exactly; settings from monitor to monitor are different, and certain brands, as well as most cheaper flatscreens, are known for sometimes misrepresenting certain colors.

If you like, I can make another version, with deliberately reduced greens; it may make the colors look a bit odd on most machines, but if your monitor's over-representing green, it should work out.

As a reference; the color that I get from the dress panels, which seems the most common and least affected by shadows and highlights (Difficult, since the yellow panels are all curved, every one) is, on the RGB scale, 170, 190, 40(MUCH less blue, a purer green/red mix; yellow). The blond hair matches your sample more closely; is this what you were talking about?

EDIT:Also, the hair has increased blue because all the colors together make white; I was aiming for platinum blond. Red and yellow being close together, raising blue should merely lighten the color. (Of course, I was operating with Magenta, Cyan, and Yellow in my adjustment layers, but the outcome is the same.)
