Snow, like water, absorbs red and yellow light while retaining blue light, giving it a bluish look. When the snow is just a few inches thick, no light is trapped under it, making the snow appear white. The more snow there is, the more blue light remains.
Answer: So, why is the snow and ice blue? Similar to water, snow absorbs red and yellow light, leaving blue light behind to give it that bluish appearance. If snow is only a few inches deep, none of the light will be left behind, making the snow appear white. The deeper the snow, the more blue light is left behind.
