If you purge the colors, you see black. You have to add up all the colors to get the white.
This tells us the greatest of Spiritual Truths;
The Sun as metaphor for God is the Pure Light seen as white.Black is the darkest color, the result of the absence or complete absorption of visible light.
light contains all Colors, all the wave lengths, thus God is all the names given by the Messengers.
We have a Hidden Word to meditate upon on this subject
"O CHILDREN OF VAINGLORY! For a fleeting sovereignty ye have abandoned My imperishable dominion, and have adorned yourselves with the gay livery of the world and made of it your boast. By My beauty! All will I gather beneath the one-colored covering of the dust and efface all these diverse colors save them that choose My own, and that is purging from every color.
To me this is that when we see that we have One God, that Light from the sun is the source of all life on this earth, then we have been purged from the colours, that are the distractions of this material world.
We then live this life in our Diversity as the flowers of one Garden, doing good to each other in the knowledge of the bounty of the sun, the light that sustains us.
Gives us a level of humility to know those that worship the sun in the past, had a very strong foundation in Faith
