'Bela Lugosi' (BL) like most purples, actually like most daylilies that have red or purple coloration from anthocyanin pigments, is quite variable in flower colour. Below are photos of its different looks seen in my field in different years or sometimes at different times of the same year. These depend on temperature or the amount of sunlight or both. None of these photos have had their colour manipulated with software and they are as close as to the actual colours shown in the field as digital cameras show. BL can look normal in my field but I have never taken a photo of it when it was.
A look at a single petal in higher resolution to show some dotting.
