- Today's bright sunlight charged up the garden solar lights. So the oh so real blue sunflower is backed up by the orange globe. The sunflower is a real tacky LED marvel of modern science as it changes in color from red to purple to blue to green before repeating the sequence. Odd as it is, there is no yellow. Canon 7D, 1/60 sec @ f/2.8, ISO 1600, 70mm focal length.
