Your physical features are a part of your outfit. When you are pulling a look together by repeating the colours in your outfit, consider the colours of your hair, eyes, and skin tone, in addition to your clothing, footwear and accessories. 

Black and brown shoes are great with black and brown hair. Cream, gold, tan, taupe and toffee are with blondes. Bronze, burnt orange, cognac, and animal print with redheads. White and silver with grey hair. Brights can bookend rainbow hair.

Bookending is not the only route to outfit cohesion. Dark hair can be great with light footwear, and vice versa. You don’t need to have rainbow hair to wear non-neutral shoes. Your colour and styling preferences are more important than bookending.
