| I have a bunch on photos of my dog in which her eyes are doing that green glow thing. Does anyone have any suggestions about the best way to fix that? |

| Many photoediting programs have some features to edit redeyes and you should be able to do it for other colors. Think it works pretty similar to color replacement pencil which you could also use. |

| Most automated software for this purpose is optimized for red-eye, not green-eye. In Photoshop, use the sponge tool at about 90% to desaturate the green areas. That'll fix it. |

^Agreed, although I use around 50%.
Sometimes I'll also use the lasso tool or the pen tool to make a selection around the offending area. Then I'll use one of several filters to make it look more natural. Brightness/contrast or Hue/Saturation always work well for me.

In Photoshop you can use this for red-eye (slight modification for green-eye). Automated systems work but this works just as well and you gain finer control over the whole process.
Instead of working with layers, you want to work with Channels. Each color photo in RGB mode has 3 layers and 1 composite. The Red, Green and Blue. Since the Green layer contains the largest portion of data in the spectrum that humans see, most digital cameras sample the green spectrum 2x (Sony took advantage of this to create the Emerald channel).
1. To remove red-eye you can choose the background layer of the photo.
2. Switch to Channels.
3. Select the Green Channel (turn off all other channels.
4. Use the lasso tool (or polygonal lasso) to select around the first offending eye.
5. Hold Shift and select around the 2nd offending eye.
6. Feather the selection by about 5 pixels depending on the resolution of the original image (Select | Feather Selection).
7. Copy (Edit | Copy)
8. Reselect all the channels by clicking on the composite channel at the top of the list.
9. Go back to the Layers menu.
10. Create a new layer (I use the New Layer button at the bottom of the Layers window).
11. Paste the Green eyes into the new layer (Edit | Paste).
12. Edit the opacity of this layer to get it to blend in with the "red-eye" layer without giving too much green.
For green eye I'd suggest trying a similar methodology but with the red or blue layers.
