I'll save time and repost what I posted in another thread:
I don't think there's much danger of IDW giving them lettered belts but I do have the sinking suspicion they're strongly leaning towards giving the TMNT different colored bandannas. Don't. Please. I don't ask this as a Mirage purist, I strictly ask this out of logic and good sense. I mean, hell, give them all BLACK bandannas (or no bandannas) if you must, but whatever you do do not give them rainbow/mood-colored ones. Unless the IDW universe will be so drastically different from the Mirage universe that the TMNT will no longer be a ninja clan, ninja clans have one color (or no color at all). As soon as you enter into account a ninja clan with members all picking different mood-colors for their bandannas to make metrosexual fashion statements or to say, "I'm different!" then the whole thing becomes a sham. I don't want the TMNT to be a sham, do you?
"But I have trouble telling them apart when they don't have different colored bandannas!!!"
#1: A lot can be achieved in artistic variation of the Turtles in body types, facial features, and even skin tones (though varying the skin colors too much becomes odd when it's too drastic... they're all supposed to be red-earred sliders and brothers, and it's not like you'd ever see a brown red-earred slider come out of one egg and a forest green red-earred slider come out of the one next to it). And it's not often that you see a Turtle without his trademark weapon anyway.
#2: It's possible you're a moron. Sorry.
"But in all the TMNT spinoff universes they have different colored bandannas!!!"
#1: That's neither the source material's (in which they all wore red) fault, any reflection on the source material, or any good reason for IDW to have to bow to it as well for their own TMNT universe.
#2: Why should the IDW universe (which, from indications sounds like will be built from the ground up) need to concern itself with or be beholden to what was seen in some children's spinoff universes? Plus with the latest children's cartoon from Nick sticking with the spinoff motif of rainbow colored bandannas for the TMNT, wouldn't IDW want to do do what they reasonable could to set their new comic apart from it? (especially since I think the idea is that IDW would run their own TMNT comic and universe and seperately print a Nick TMNT comic?)
#3: The spinoff universes are geared for little kids and otherwise had to be toy conscious ("buy me the blue one, Mommy!"). An IDW TMNT comic need cater to neither.
"Aw, c'mooon, guys... I really, really, really liked the children's cartoons when I was like 6 and to me Leo will always be blue, Mikey orange, and Donnie purple!!!"
#1: You can get all of those cartoons on DVD and rekindle the sanctity of your childhood at your leisure.
#2: Correct me if I'm wrong but IDW is starting a brand new TMNT universe in comics untethered to anything before it. If they're already set on throwing in things "just because they were there in the cartoon" spinoffs, then why should they even bother with a new universe at all? Why not just pick an existing universe and roll with that?
"Who CARES what color their bandannas are?!?"
You should. That is, if you don't want your TMNT to be a sham.
