Thank you Kathie! Is this the Platinum blonde? The blonde and redheads look the same to me.

The differing shades of blonde, including platinum, didn't start until the bubblecuts and #6 ponytails. Redheads (or 'titian' as it was called at first) were first introduced with the #5 ponytail. Numbers 1-4 had two hair colors -- blonde and brunette.
