The sky is blue as result of the density of our atmosphere.
When light leaves the sun it's white, but white light contains all colours.
The atmosphere acts like a filter allowing only blue light through.
Respectively if our atmosphere was thicker or thinner then the sky would be a different colour.

Honestly, next time you ask a question, check to see if it has already been asked. This is such a common question that when you type it in the "Enter your question" box you are shown at least 5 duplicates of it that have already been posted. Save yourself some points next time and research first.
