Your hair color (natural or otherwise) can have a big impact on which glasses frame colors will work best for you. Consider not just the shade of your hair (brown, blonde) but also whether your hair has cool or warm undertones.
For glasses, warm blondes can run the gamut of warm colors including Hemlock, Tortoise, and Peach shades.
Blonde with Warm Undertones
Warm blondes have honey and bronze tones in their hair, and are generally slightly darker.
