This question may have us ask when childhood, however, perhaps we were not given an explanation.
Outer space is actually colorless. Meanwhile, the Sun emits bright light and golden.
The blue color of the sky is caused by the interaction of the atmosphere and sunlight. Quoted from Live Science, white light, including sunlight, made of particles of light with different colors. Each has a corresponding wavelength.

For example, if the sunlight through the transparent objects such as water, light waves will be biased or curved. Because of the light change speed while switching from one medium (air) to another medium (water).
Prism
splitting white light into color elements. Due to different light waves refract different color in each viewpoint. Meanwhile, the colors move in different speeds while penetrating a prism.
Prisms refract white light in a spectrum of colors. Alternatively, how objects, such as mirrors, reflecting light in one direction. While other objects can make the light scattered in all directions.
The blue of the sky is a result of the type of deployment is called the 'spread of Rayleigh', which refers to the spread of light from the particles are small. Only one-tenth of the wavelength.
Rayleigh deployment is very dependent on the wavelength of light, with a wavelength below the most widely spread. At the bottom layer of the atmosphere, the particles mini oxygen and nitrogen molecules deploy short-wave light, such as blue and indigo color spectrum, to a degree greater than the length of light waves, such as red and yellow.
In fact, the deployment of a 400-nanometer light (indigo) 9.4 times wider than the deployment of the 700-nanometer light (red).
The spectrum of color and light wavelengths. Although the particles asmosfer deploy more indigo than blue, blue color that looks because our eyes are more sensitive to blue light. Tilapia also because some of the light has been absorbed by the upper atmosphere.
When the sunrise or sunset, the sunlight through the atmosphere is stronger. This resulted in a light blue and indigo spread again, and the light shows red and yellow glow. This is to show a tinge of orange in the sky.
