Raindrops behave as tiny prisms which refract the short wavelength blue-violet rays more then the long wavelength red rays. With the Sun at our back, we see a rainbow with the blue-violet toward the center and the red above. There can be a fainter second arc, with the colors reversed, red inside the curve of the arc.<br /> <div class="Discussion_UserSignature"> <font size="1" color="#3366ff">www.siriuslookers.org</font> </div>
