Here are a few suggestions I put in the database forum - but I don't think Dave has seen them yet, as he has not responded.
"Do you have a current model of what the color choices for blooms will be?
I am wondering how that will work for daylilies.
In daylilies, off the top of my head, I would think of white, cream, yellow, gold, polychrome, peach, apricot, melon, orange, red, burgundy, pink, pale pink, mauve, magenta, lavender, orchid, purple, blue (not really, but some people think so!), black
Then we have patterns - watermarks, eyes, pencil eyes, stippling, streaks, different color edges, edges without eyes, halos
and, forms - various spider forms and also the new sculpted forms, as well as a couple types of doubles, and also polytepals."
