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 remainbright,
and white ones become luminous, shining like ghostly figures
against a darkening green background.
~ Rosemary Verey, The Scented Garden, 1981
