I came across this and thought a few might find it helpful. For those doing portraits, sometimes lighting and such makes for some odd skin tones, and this page provides some Photoshop hints along with a JPG of the some standard shades. That image can be used as a comparison standard in other editing programs as well and so might be worth copying. The program I use, Picture Windows Pro, uses that image in a different way, and I assume Paint Shop and others can use it in one way or another.
The image is on this page:

If you have a still life and the lemon looks more like a lime or an orange, use a clip of what you think is most likely to be a pro-grade image of a lemon (the one that went through big-bucks gear in order to look realistic, not necessarily the one that looks best on your particular monitor) and use whatever tools your program offers to push the colors your lemon around to correspond to those on the "real" lemon.
