Did you ever wonder why the sky is blue during a clear and cloudless daytime? It's because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colors because the blue light has been scattered out and away from the line of sight.Here are some photos of a blue sky.
