All the bright colors of the rainbow merged into one, it is really true! Rainbows that we see from time to time in the sky, usually before or after a rainstorm actually consist of pure white light that is refracted by the water droplets in the air. When we speak of pure, white is a "pure" color. Usually it is associated with cleanliness, kindness, chastity, or even holiness! What a better compliment to someone special than a lush bouquet of white lilies, roses or carnations?
