When I was little, there's was a carved portrait of St. Martin de Porres on a particular wall in my room. I used to think that the guy in the carved portrait was actually what God looked like. So, to me, God was a black man wearing white robes. However, I had a kid's Bible of the white Jesus variety (to those who still don't know: Jesus was a Middle Eastern man, what with being a Palestinian Jew and all) so I thought Jesus and all other characters from the Bible were actually legitimately pink people with funny noses. Thus, the Holy Trinity: black God, pink Jesus, and a white dove for the Holy Spirit.
