Color text returning white

Hi, i have this code

public IEnumerator SinDinero(Text Dinero)
{
   
    Dinero.color = new Color(255, 0, 0);
    yield return new WaitForSeconds(2);
    Dinero.color = new Color(246, 242, 13);
        //TODO Tiempo de espera

}

As expected the text color change to red but after the 2 seconds it changes the text color to white insted of yellow. any ideas?

Color values are 0.0 - 1.0, not 0 - 255. Either that or use Color32.
