I have the same color combo on my truck. As far as answering your question I don't really know. Since there is no paint code for this combo you're guess is as good as mine.
On my ID plate where the paint ID is usually stamped mine is stamped "SPEC". Is yours stamped this way as well?
I have always assumed that it was Anniversary Gold and Bombay Ivory. The ivory color on mine seems lighter than the Honey Beige that I have seen on some of the Impalas.
If you find anymore info about this color combo please let me know. I'm curious is yours a 3100 or a 3200?
