You know, it would be interesting to see what the four turtles look like if they mutated fully into humans, even if just for one episode before changing back. None of them would wear their bandanas, but their human clothes would give at least a subtle nod to their bandana colors; their outfits wouldn't be all one color, or that would just look ridiculously color-coded.
 * I always imagine Leo looking rather Asian with jet black hair, but still having blue eyes; he could look "racially ambiguous." If he had to wear human clothes, I imagine something simple, functional and dignified, generally kept clean and tidy.
 * I kinda imagine Donnie being a black guy for some reason, even with his relatively high-pitched voice. He would be reasonably handsome, but still come off as a geeky ball of OCD.  If he had to wear human clothes, he'd probably dress practically for the occasion, without worrying much about fashion.
 * Raph could have brown hair and a Mediterranean complexion to go with his green eyes. And no, I don't think of him as a guido, but he would be a showoff, wearing a tank top (red, maybe) and otherwise generally showing off as much G-rated skin as possible without looking trashy.  He's vain and self-worshiping as a turtle, so naturally he'd be vain and self-worshiping as a human too.
 * Mikey could have blond, sandy or ginger hair and pink "Celtic" skin to go with his freckles and baby blue eyes. Even if he had red hair, I think it would be better if he didn't look like he could be April's little brother, but have just enough conspicuous differences to look at beast like first or second cousins.  He would have straight hair, but it would be permanently unkempt.  If he wore human clothes, they would be as casual as possible, with little actual thought going into what to wear.  If there is any other regularly exposed skin besides his face, it would also be freckled due to sun exposure.  Celtic skin just cannot tan.
