Several years ago while researching something unrelated to "muddy" a friend suggested I read an article by Jim Brennan in the Summer 94 issue of the Daylily Journal ( AHS members can access this issue through the portal) which included information about the color brown seen in Milk Chocolate. Jim thought the brown color was from lavender over orange but when looking at the cells under a microscope found instead that the upper epidermal cells had a dark "glob" of pigment possibly from an insoluble concentration of lavender pigments.
The article always comes into mind whenever I'm thinking about mud in daylilies and how "muddy" and the brown color seen in daylilies like Milk Chocolate could be something completely different. I don't know if Jim or anyone ever did more research into the color brown...
