"Colors change; in the morning light, red shines out bright and clear and the blues merge into their surroundings, melting into the greens; but by evening the reds loose their piquancy, embracing a quieter tone and shifting toward the blues in the rainbow. Yellow flowers remain bright, and white ones become luminous, shining like ghostly figures against a darkening green background." ~ Rosemary Verey, The Scented Garden, 1981
