I know it would be more expensive to paint vs. powder coat but I would paint the cage to match the body. I agree with olympicmountain, that color is too dark to powder coat the cage black. I HATE to paint tubing and such like your cage. It is a giant pita. Easy to miss spots and lots of wasted paint. Oh, and I love the color. My work truck super duty Ford is just about that color but maybe a shade lighter. The only thing I don't like About that color is that it shows dust and grime as bad as black. I live on gravel so it would never look clean.
I like the cage design also. It is built off of the original sport bar? How much head room do you have in the front?
