By now you've probably seen clips of Arizona Governor Jan Brewer during last week's debate. She wore yellow:
The governor's hair and skin tone are already very similar. With this yellow shade, which is much brighter but has similar undertones, her hair and face look more yellow as well, and her eyes look very dark in comparison. She sort of glows, and not in a good way.
She would have done better with a lighter, cooler yellow, or even just a switch to blue or green.
