Okay, the colors on my new 40D are all out of whack

I am a gigantic moron.

I just realized the 350D's white balance has been shifted to G5 and B4 since I owned it. Sorry for wasting everyone's time :)

I reset the 350D to 0,0 white balance, and now that they're truly operating at the same level, the 40D is the clear winner - colors are more vibrant, ISO noise is lower, and the colors are more accurate. If I shifted the 40D to G5, B4, I'm sure I could get the "accurate" green color of that blanket just like the 350D was at G5,B4.

Again - sorry :)

Did it happen in every shot, assuming you took more than 2? could be the lighting for example.

Yeah, I tried it several times and had the camera in the exact same position - the lighting didn't change.

go into your menu and check to see that white balance shift hasn't been used.

Its like your green channel is low. Hmmm....did you look a red, green, blue histogram and what did it show for the green channel.

Good suggestion. And if it's on zero, experiment with setting it so you like the results. That's why it's there...

Is this just a problem when shooting under incandescent lights? Are the colours out when you shoot in daylight?

I would try setting custom white balance with both cameras using a gray card as a reference. If there is still a discrepancy, then I'd suspect the 40D might be out.

I haven't had time to test it in all situations yet - it's raining outside today.

The camera is supposedly under a 90-day warranty from Canon from being refurbished. If the camera is bad, is this something they'd cover?

Take a RAW shot of the same scene with each body and process identically in PP. Compare.
This will eliminate any differences due to in-camera settings.

Exposure looks different. I actually prefer the 40D shot, the 350D shot looks too green to me.

The 350D is an accurate representation of the color of the blanket - the 40D is waaaaay off.

What are the exposure settings? Your EXIF is missing.

Also, can you post images that have no PP done at all?
