The thread between father and daughter is violet, with hues of extravagance when the violet is saturated, frustration when darkened, and magic when brightened. The thread between mother and son is red, with moments of strength when ignited, danger when flickered, and desire when cooled. Between friends, the thread is chartreuse that mimics growth and healing. Between lovers, orange implies the sensation of heat, and symbolizes endurance when mixed with yellow and pleasure when mixed with red. Between ex-lovers, azure is the color of the sky, mist, eyes, and steel. Strangers and the estranged are treated similarly with yellow and gold, the color of bittersweet, cowardice, and imagination.
