But if you went to the top of the highest mountain， went to the top of the highest mountain， where there is less air between you and the sun to scatter the sunlight， the sky would be deep， dark blue. And if you rode in a rocket high above the earth， where there is no air at all to scatter the sunlight， the sky would be so dark that it would be black. Sometimes the sky doesn't look blue.
