Flats tend to have a less “dressy” appearance than high heels, so in order to make them stand out, they have to be a little “blingged-out”. A metallic color like silver or gold accomplishes this very well. Silver also goes with almost any other color, so it’s a good choice in that respect. For a fun but formal occasion like a prom, they could be ideal, depending on the outfit you intend to wear on the big night.
Here’s an example of a silver flat that I find pretty funky:

When it comes to clothing that is shiny, you don’t want to overdo it. A metallic pair of shoes is plenty. Silver jewelry is fine, and maybe a metallic purse, but that should be enough. Silver shoes or accessories look great when paired with a white or a gray dress. They look especially good if you are dressed in black. Silver reflects other colors, and so it tends to always look good no matter what other color you pair with it.
