Hmmm, I'm thinking, Debra. My first thought would be
to try a yellow. Something like JT Davis or Spectral Elegance.
Or maybe a melon. The dark eye is more than likely going
to show up, but perhaps lighten it a bit with yellow. The dark edge too.
Depends on what you aim for. Would you want to darken the eye
and edge, and cover up the brown with perhaps an almost black
eye and edge?
I have a seedling that is in the tawny category that I am thinking of
pairing with yellow. I don't care for its brownish color, but I like its shape, and
it is hardy. I definitely want hardiness, even if I have to take some newer
ones backwards a bit, before going forward again.
I'm going to look back at all your photos and think some more.
This kind of thing is usually a toss up with experimenting.
I just noticed you mentioned Samuel Bell in one of your posts. That might be an interesting combo.
