Did you know that sunrises and sunsets are visually identic, but we can perceive them differently? This is because t sunset, our eyes are daylight adapted and when the light fades, we cannot adapt as fast as the sky darkens. Some hues may be lost or perceived in a manner peculiar to sunset. At sunrise, however, the night's darkness has left us with very acute night vision and every minor change in the sky's color is evident.
