/**
 * Returns an RgbColor or RgbaColor object. This utility function is only useful
 * if want to extract a color component. With the color util `toColorString` you
 * can convert a RgbColor or RgbaColor object back to a string.
 *
 * @example
 * // Assigns `{ red: 255, green: 0, blue: 0 }` to color1
 * const color1 = parseToRgb('rgb(255, 0, 0)');
 * // Assigns `{ red: 92, green: 102, blue: 112, alpha: 0.75 }` to color2
 * const color2 = parseToRgb('hsla(210, 10%, 40%, 0.75)');
