Come rain and shine, the rays of the sun paint the crimson sky, vivid colors of different hues with the brush of perfection

From one spectrum of light emerged the ROYGBIV, standard colors of the rainbow

A gene of human into seven races, seen through the minds eye, not as one of mankind, but of ours and theirs, cast and creed, rich and poor, intelligent and ignorant

Clear the mind with the whiteness of the soul and merge the colors of man.
And you see a beautiful garden of earth with various species of decoration that make the world an interesting place to live

For a world with only one color, would be a boring world run by robots.
