Clear: God's favorite color

Perhaps trying to cheer me up in the midst of new-semester distress, the same guy who apparently relishes tidying up around here, and wished me a happy weekend on Thursday, recently remarked on how smart God is. As evidence, he cited that God made air, which we can't see, and water, which we can see through. I gather that the more transulecent or invisible something is, the smarter you have to be to have created it, or the more weighty it is as evidence of God's influence. Now I can't stop thinking about stripper shoes and ice sculptors and saran wrap, and their relative holiness.
