The OP's posterized image is a JPEG. JPEG compression will create new colors.

Lets hope that OP is not using that one then.

Hey Everyone, I wanted to thank all of you for taking the time to provide input on my question.

Sorry about the image provided being a JPEG.  I didn't think about the ramifications regarding color.  I am still using Gimp 2.8 and my posterize seemed to be working correctly.

I'm looking for a way to automate the process.  I would like to create a python-fu script to create the original image, posterize it, and then split it into separate layers.  I would then like to bump map each layer and create a drop shadow for each layer.

Ultimately, I am trying to create the following type image (and then automate the process).

   

Thanks again for your useful comments!!!
