However, whenever I take pictures of people in incandescent light the red channel is totally over-saturated. Sometimes to the point of blowing out. Skin looks bright red instead of natural. I have to reduce the red channel saturation in Aperture by about 20 points for the images to look ok.

White balance is not the issue: I set it to the incandescent preset (auto white balance is hopeless in incandescent light, but spot on in other lighting conditions) and tweaking the color temperature in the RAW file makes reduces the red saturation somewhat, but makes all other colors look wrong.

So, is there a way to set the K20d to reduced saturation in the reds, but leave the other colors unaffected? I don't want to have to post-process all my shots.

Do like in the old film days. Use a tungsten correction filter (bluish) and a custom white balance.
Color compensation filters...: Nikon D3 - D1 / D700 Forum: Digital Photography Review
BTW: AWB doesn't go into the 2600K range that is tungsten.... see your manual.
FILTERS work...

Nicely done. I convinced myself of this with similar tests years ago, and have long been an advocate of white balancing filters.
