Exposed in 6-steps why is the sky blue?

Sunlight is made up of many colors—red, orange, yellow, green, blue, indigo, and violet.

Each color has a different wavelength.

Blue and violet light have shorter wavelengths, while red and orange have longer wavelengths.

Even though violet is scattered more, our eyes are more sensitive to blue light

and some violet light is absorbed by the upper atmosphere.

So the sky appears predominantly blue to us.
