This last one won't display in Firefox, because it's a CMYK jpeg. But on Mac OSX, it displays with the exact colors (eyeballed) that the original larger image had.

This is what I get when I try to do the CMYK -> RGB conversion via image magick (strangely, Gimp gives a nearly identical result).



This is what the printshop folks get, if they convert to RGB manually in photoshop, the process I'm attempting to automate. It's not perfect compared to the original, but it's superior to my own.



Now, I've improved my conversion considerably... I wasn't setting the colorspace and profile correctly at first, and the black was washed out to this dull indigo blue. I've since fixed that... but the difference in the pink colors (and even the black not being quite black enough) tend to make me think I'm using the wrong profiles.

Can anyone clue me on what I might be doing wrong? The boss is starting to get peeved...

You don't give an example of what you are doing, so we can't tell if it is wrong.

However more than likely you are not giving a good input profile that matches the image.

see the (recently formated may take a day to appear) profile handling section of IM Examples, yes it is command line, but you get it right there you can then program it in correctly.
