But if you push deeper, you will discover a world. the more you explore the more you are amazed by vibrant colors, wild jungle of personality layers. you will find Black as the most compelling color. Black is the Unknown. It attracts, it pulls you in. The Unknown motivates you to explore. Love is exploration of the Unknown.
