Thank you Maurice. I know in some other plants the anthocyanin pigments can 'burn' off in sunlight. A bloom that is pale pink or lavender when it first opens can be near white a bit later if it's in direct sun. When that tint is overlaying another color, then the presentation of the underlying color is different. A 'muddy' bloom might not always appear 'muddy' even on the same day.
