That's a recirculating heater and appears to be the same color as mine, although I don't have that round part sticking out to the left on your second picture. According to Brad Allen, there were some that were the bluish green color and most were the hammered bronze like Eric's (2 posts above yours). One of Brad's pics is of a blue-green heater. I haven't attempted another color match on mine, and may just go with the hammered bronze instead.
Bottom line, if it doesn't appear to be repainted, then it's "correct."
