Air is transparent, however, blue (high frequency) light scatters much more easily than red (low frequency) light, in a process known as Rayleigh scattering.
Blue light is scattered heavily, so that it hits your eyes from every direction at once. Red light is barely scattered, so it hits your eyes from only the direction the Sun is in. Hence the Sun appears whitish-yellow, while the sky appears blue.

The nitrogen and oxygen molecules in the atmosphere scatter the short blue wavelengths of the sun's light so that it "rains" down on our eyes in nearly all directions making the sky appear blue. The longer yellow, orange and red wavelengths are not scattered in that way by those molecules.

Because blue is easy to see from the white light in empty spaces. This is because it's shorter than other sorts of light. The same is true for water.
