They are all the soul, and skin color lies on a circular continuum starting nowhere in particular and ending at the same place. You have not completed your journey around the circle, however, for as you continue to travel, you find you pass through less and less lightness until you finally reach black. All entities upon the circle are unique unto themselves. All entities travel reality within a machine of various degrees of color. All machines carry a portion of God, irrespective of the color of the machine.
All machines carry a soul, which has no color.
All souls are companions through God, through a commonality of being souls, portions of God Itself, portions of each other. Color is one of the more simplistic concepts in nature. Perhaps, but still no different. A man, a woman are both on opposite sides of the circle. Both are more than physical appearance, composed of obvious external characteristics.
