I’ve seen several at hospitals and other workplaces, so I don’t see why it would have any bearing on a woman’s beauty any more than a hair clip or scarf.
I had different color elastics when I had braces in the 1900s. Not much difference with colored power chains. The big thing to avoid is getting some that look like you have food stuck in your teeth.
I don’t know what a color power chain is, but I think a woman can be beautiful or gorgeous no matter what her “accessories” are. It depends on the viewer. Beauty is subjective.
Is that colored braces? Never heard of a “color power chain” but I have seen colored braces. To me, they’re like any trend. Some people may like them, some may like traditional silver. To each his own.
