Explanation:
Air looks invisible because it sends very little color to our eyes. ... Objects appear to be the color they reflect to our eyes. Air is a mixture of gases, mainly nitrogen and oxygen, with small molecules that are far apart. Wavelengths of light may pass by these molecules without hitting them.

Air is transparent to our eyes because we have evolved retinas that are sensitive to the very wavelengths of light that pass through it unobstructed – otherwise we wouldn't be able to see anything at all. Wind is just moving air, caused by pressure differences in the atmosphere.
