The pre-1982 cents were 95% copper. The post-1982 cents are plated with 95% copper. So, in theory, the surfaces should look almost the same.
Copper reacts with all sorts of stuff, and can turn a number of colors, depending on what it is exposed to and for how long.
In my opinion, both cents in your picture were virtually the same color when they were new, but are now a product of their environment over the past 36 and 19 years, respectively.
