People in air signs understand the world through thinking. For them, intangible ideas and concepts seem to be more realistic than tangible entities, so they usually have some ideal colors. Because you pay too much attention to the prospects and developments, you may fall into the trap of your own reasoning. Air signs's frequency is just the opposite of the sensory world, so even a little sound, taste and smell will bother them.
