I'm going to be building something - not plumbing - with 3/4" copper pipe. As you can see from
this image, the pipe is a different "color" than the fittings. The fittings are bright copper, the
pipe itself is much duller.

Anybody know why that is or more importantly, how to shine up the pipe so that it matches
the fittings?

Try Brasso.

That wasn't the question. Sheesh.
