Typescript solution:

interface RGB {
  r: number,
  g: number,
  b: number
}

const str2rgb = (color: string): RGB => {
  const rgbSubset = color
    .split('(')
    .pop()
    ?.split(')')
    .shift()
    ?.split(',')
    .slice(0, 3)
    .map(Number);

  if (rgbSubset && rgbSubset.length === 3) {
    const [r, g, b] = rgbSubset;
    return {r, g, b};
  }

  throw new Error(`Invalid color = ${color}`);
};
