This is dedicated to my Fellow Asians ;)
Strictly speaking, white is not a color, but the manifestation of the presence of all color - the complete energy of light. It stands for wholeness and completion. In many cultures it represents openness and truth. White has a cold quality. It can provide clarity as its energy is complete.
Put some white in your life when you want:
to clear clutter and obstacles away
to start a fresh beginning
to bring about mental clarity
purification of thoughts or actions
