We had a female with a blue head in our pond, then a male turned up for a couple of years. He disappeared early last summer and hasn't turned up yet this year. He's pictured below, the calling pic is from 2013, the other from 2012 (fairly certain it's the same male, he grew considerably between years but the markings seemed to match).
There's at least one other location near me that has bluish Green Frogs, so I don't think at least partially blue specimens can be too rare. You might try contacting local herpers to see if there are any locations near you. You may have better luck sifting through pond tadpoles for a blue one if there are blue adults in the area.
