The word "silver" can be said to symbolize senescence, the symbolism of which is mostly drawn from the color of one's hair (the parlance silver-haired), since, often correspondingly, the density (or absence thereof) of grey, or silver, in one's hair will roughly estimate their vitality, fertility and youth. A tenuous connection and weak hypothesis at best, but still an existent one. It could be homage to Mr. Stephen Silver, large-scale animator of Kim Possible, but the modifier hampers the chances of this.
