Here's an adaptation of CD Sanchez' answer that consistently returns a 6-digit colour code:

const stringToColour = (str: string) => {
  const hash = 0;
  str.split('').forEach(char => {
    hash = char.charCodeAt(0) + ((hash << 5) - hash)
  })
  let colour = '#'
  for (let i = 0; i < 3; i++) {
    const value = (hash >> (i * 8)) & 0xff
    colour += value.toString(16).padStart(2, '0')
  }
  return colour
}

If you are using Eslint, you want to wrap this function in the

/* eslint-disable no-bitwise */
>> stringToColour func. definition here" <<
/* eslint-enable no-bitwise */

Usage:

stringToColour("greenish");
// -> #9bc63b

(An alternative/simpler solution might involve returning an 'rgb(...)'-style colour code.)
