I agree with Scott... get the color for YOU... not anyone else. Not everyone is going to like your color choice, but guess what? You're the one driving a Camaro... where is theirs?! Oh, that's right... THEY DON'T HAVE ONE...
That being said... I'd say you should pick your favorite color. I do agree (as I've stated many times here) that silver is kind of "plain" and blends in... BUT... the SIM with Black rally stripes looks damnnnn good! I think that is the perfect accent for that color, and also lets it stand out a bit.
But if you're looking to "stand out" I'd go with something that really pops. Yellow is always an eye-catcher, but personally I don't like how it looks up close... it's just too flat. Same goes with Victory Red. Both of these colors will grab attention, but they don't have the luster and shimmer of the metallic colors.
IOM and ABM are two that seem to get a lot of attention due to their multi-personality disorder (

). Both look great from afar, grab your attention, and then look even better up close when you see the metallic flakes. They also change shade in different lighting conditions. Of course, I'm personally biased toward ABM, but only because blue has always been my favorite color (see???), and I've never really liked orange on anything. But I must admit... IOM with CGM rally stripes looks gooood...
I haven't seen RJT in person, but I do agree that it looks like more of an "old-person" color that belongs on a luxury sedan. Case in point: when I showed my family the paint samples, my dad's favorite was RJT, haha. But I also agree that it doesn't have the "bad-ass" factor to it. I do think it's a really nice-looking paint, but it's just not for me. But as someone said earlier... NO ONE is going to dog you for it if you choose it... I mean... it's a CAMARO
Black, of course, is the ultimate bad-ass color. It just looks so mean and awesome... I love it. But I do feel that it hides the lines of the car somewhat. Plus, my past 2 cars have been black, and let me tell you... black looks AMAZING when it's freshly washed and shining... but it doesn't last long. You'll see every bit of dirt/dust/raindrops... everything. So keep that in mind also.
So, looking back... my post is actually not very helpful at all, lol... I guess I'm basically saying that there is no "wrong" color. I've always hated red, yellow, silver, and gray cars... always. But every time I see the new Camaro, no matter what color it is, my jaw drops. They all look incredible! So choose what you want, and don't listen to anyone else!
