The sky at sunset is a sight to behold. The colors are often so vibrant and beautiful that they take our breath away. The colors of a sunset sky are caused by the way sunlight interacts with the atmosphere. When sunlight hits the atmosphere, it is scattered in all directions by tiny molecules of gas and air. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. A color pixels custom cursor with Sky Sunset Pixel.
