Trouble Photographing Urethane Eyes

the hair of your doll shadowing the eyes to much. Try photographing her with a light frontlight (desk lamp,flash against piece of white paper which you place at your dolls feet etc.)

 

If the color seems "off" it is almost for sure a white balance
problem.

If your camera supports RAW capture use it and include a
standard gray card in one of the shots so you can use the
white balance tool in your RAW conversion program to set it
correctly.

Also be sure that the eyes are lit from the same source as
the doll's face. In your second image above they are in shadow
so not the same light as the rest of the face.

If you're lighting from above you might consider using a reflector
to fill the shadows adding light to the eyes.

 

The incandescent bulbs appear to throw a warm (yellowed) light while your light box, camera flash, and retouch software probably throw a more cool or pure white illumination. Try changing out the lamps of the lighting you use when photographing her to "warm white" or photographing her in natural light where greens and blues in the surrounding setting will bring out the rich green of her eyes. If that turns out a good result in the eye color without a lot of touch ups (& bleaching) being necessary, then the color balance is more of the issue than the white balance. Direct yellow toward the eye, so that it catches the green and gets reflected back to the camera. If you don't want the yellow to clearly appear on the rest of her, you could use the white light sources farther back to keep the rest of her illuminated "white" while the eyes still get hit only by "gold."
A quick way to try it is with a handheld flashlight with warm white beam. Don't hold it *too* close, just get that yellow into the eyes so the camera sees it.
