Dear All:

The discussion regarding color is fascinating. Comparing the color of a
flower with a color chart should be done in northern and bright light,
not sunlight. When deciding on the merits of a new lily as a cut flower,
we always made sure they looked good under fluorescent light, as such
was that used by florists in their windows and shops. The difference in
the perceived colors under such different light sources can be quite
startling.Cheers, John E. Bryan wrote:
