When the Sun light enters the atmosphere, the wave length of the blue light is roughly on the order of the size of the atmospheric molecules - hence the blue light gets scattered. So the sky looks blue when viewed from the surface of the Earth, and if you subtract blue light from white light, you get yellow - which the color of the Sun light when viewed from the surface of the Earth. | |

When the light level is low - as during night or in a dark room - you see contrast only, which results in a black and white image. Therefore the sky during full moon would appear dark rather than blueish. | |
