/**
 * Converts a RgbColor, RgbaColor, HslColor or HslaColor object to a color string.
 * This util is useful in case you only know on runtime which color object is
 * used. Otherwise we recommend to rely on `rgb`, `rgba`, `hsl` or `hsla`.
 *
 * @example
 *   background: toColorString({ red: 255, green: 205, blue: 100 }),
 *   background: toColorString({ red: 255, green: 205, blue: 100, alpha: 0.72 }),
 *   background: toColorString({ hue: 240, saturation: 1, lightness: 0.5 }),
 *   background: toColorString({ hue: 360, saturation: 0.75, lightness: 0.4, alpha: 0.72 }),
