The Silvers are those born with silver blood, which gives them supernatural abilities. They are treated as gods and served by the "lowly Reds." Though they classify themselves as higher than the Reds, they also have a hierarchy within their society: the common Silvers and those that belong to the high Silver Houses. In Broken Throne it's theorized that the Silvers gained their abilities from the remaining effects of the Calamities.
Silvers have a pale undertone to their skin and are considered to be extremely beautiful. When they blush, their cheeks pale because of their silver blood. They walk elegantly and possess a lot of grace. This is due to the fact that they are trained from an early age to have socially appropriate behavior.
