White is associated with purity because the entire spectrum is functioning in unity. White is a healing color. White is appropriate for weddings because the unity of male and female symbolizes the unity of allness.
The color white is the absence of memory.
White is the color of decomposition. White is also no color. White is nothing. In photography, the paper is white, next comes the light, which is also white, then the shadow is created, the apparition.
White. . . is not a mere absence of colour; it is a shining and affirmative thing, as fierce as red, as definite as black. . . God paints in many colours; but He never paints so gorgeously, I had almost said so gaudily, as when He paints in white.
Perfect love is to feeling what perfect white is to color. Many think that white is the absence of color. It is not. It is the inclusion of all color. White is every other color that exists, combined. So, too, is love not the absence of an emotion (hatred, anger, lust, jealousy, covetousness), but the summation of all feeling. It is the sum total. The aggregate amount. The everything.
