Pick random array element from string, but same string always returns same element. Pseudo-random

I have an array of possible colors in Javascript:

possibleColors = [
        "#10ace3",
        "#f26529",
        "#c62328",
        "#e53434",
        "#ffba49",
        "#99c24d",
        "#7e1d1d"
      ]

Given a string (the person's name), I'd like to always pick the same color, randomly.

As an example:

"Sergio" would always return the first color.
"Daniel" would always return the fourth color.
etc.

Any suggestions on how to do this? Please don't take my example literally I just mean the same string should return the same color.
