To try to understand the inheritance of flower colours one needs to know the colour of the parents, possibly the grandparents and the offspring. One cannot simply change the accepted parentage and then expect to learn how the flower colours are actually being inherited.
When one reads one may always learn from what has been read. But whether what one has learned is helpful or a hindrance, is accepted or not accepted or simply is correct or wrong cannot be learned from the material being read alone.
Daylilies are not good material for 'Mendelian' genetics. In practice, in real life, many plant species are not good Mendelian genetics material. They are good material for quantitative genetics, selection, etc.
I am always happy to discuss topics/questions related to any inheritance topic including flower colour.
