Hi Cathy,
There are so many differences in the same bloom due to numerous reasons.
Cameras are a big reason. If I took a photo with 3 different cameras I would most likely get 3 different looks (coloring) to the same bloom. We had a discussion on the daylily forum awhile back about this and someone posted a photo they took and posted another photo their friend took at the same time with a different camera and there is a big difference in how they look with color. Also, it depends on the time of day it was taken. I have taken photos before the sun was up (but light out) and then gone back an hour later when the sun was more up and have 2 different colors to the same bloom. If it was taken later in the day then they may be washed out from the sun. Taking a photo early morning may mean the bloom isn't open fully so it may have a different shape somewhat than a fully open bloom.
Some cameras just don't pick up some colors well while others are more true. I had a camera that would make dark purple petunias look neon purple and pink ones that looked blue. Some creams will look super white with some cameras while others will make them look more muddy.
Another reason is soil. Soil plays a big role in the coloring of blooms. I have really high iron content in my water and I add amendments to my soil that has iron (Milorganite, ironite) and it will darken colors big time. If you go here
Daylily (Hemerocallis 'Mango Sundae') you can see what I'm referring to. The first photo is mine taken in my old garden and looks very similar to the hybridizer's photo on their website but then look at the 3rd photo. That one isn't mine, however, that is how mine looked in my new garden last year. I had one daylily (2 different clumps of it) that had an orange throat in one bed and the same plant had a bright green throat in a different bed.
Temperature is another biggie. Sometimes if temps are too cool them the colors will not be as vibrant or the bloom will not have the teeth or big ruffles or patterns it has in hotter places. And it may make the bloom be a different shape such as some blooms recurve back and kind of look like a bagel whereas in cooler climates it may not curve back and the bloom will look totally different
here's an example; it's not a big difference on this one but you can see how the one curves back more than the other. When this seedling matures more it may curve all the way back where you only see the red eye and it is more bagel shaped.
Watering and feeding can make a difference also.
