This is a ruling from the NYS Girls Basketball Officials Association for this year:

As long as the headbands are legal (single color, no more than 2” wide with only a manufacturer’s or school logo on them), allow any player to wear any color or style of headband that she desires.

This is the state's variation of the NCAA rules.

Frankly, I think too much of a big deal is made over the color of headbands.
