These oranges wouldn't have done for Tuesday but they work for today's green rainbow image.
I recently learned something interesting about oranges. Apparently, being orange in colour is more a result of cool temperatures before the orange is picked, rather than with ripening. A similar phenomenon to the fall leaf colour changes, in cooler climates, turns the oranges orange. In climates where those cooler temperatures do not occur oranges ripen but remain green. This came as news to me.
