Genesis 1:2

Started in on my next piece, which has been whispering in my head for a while now.  When I reread Genesis 1:2, it made a picture which wont go away.  The idea of the Holy Spirit "hovering over the deep".  Now I am studying and pondering how to create that.

My questions are: Is the pure spirit enough light to create some color?  There is water, but would there be some form of clouds and atmosphere?  How much?  How do I depict the spirit without looking like Northern Lights?  So....I am, of course, starting black, with an almost full globe area.  I have done well so far with black, dk blue and purple....but not satisfied yet.  Will be an interesting process.
