Here's a Kaa Eyes take on it.
i.imgur.com/omR8AhD.jpgCareful, it looks kinda bad. I just did yellow, blue, red, orange, and smoothed it around, antiallised it, smoothed, added orange to the yellow, resmoothed it, and repated until it make a semi-smooth blend. It's shitty. I know.
I can't really help you with empty eyes (that's more Mindwipe and Vann's bag) but Kaa eyes I know. Here's what I'd suggest doing:
Erase the entire contents of the eye using the brush tool's color erase mode. You'll probably wind up with some excess pixels around the border, so use the free select tool around the inside of the eye, then use the blur filter. Once the inside of the eye is transparent, create a layer underneath it, and pick a color. Any color. Fill in the eye. Then pick another color, and shrink the brush down till it's slightly smaller than the eye. This will make the first "ring." Continue this process this until you've got enough rings. (You may want to make each ring on a separate layer) If the colors look off, fenangle with the hue-saturation settings until it looks how you want it. Finally - and this isn't necessary, but I find that it makes the eyes look extra glassy - make a layer above the rings, switch to the most faded brush, and make a glossy white bit in the corner of the eye. Lower the layer's transparency settings until it looks non-obtrusive.
Here's a quick and dirty example:
