Up here, color variation on blooms is pretty normal. We experience a wide range of temperatures throughout the Winter, Spring and Summer every year leading up to the flowering season. There are many years where I would never recognize a flower from one day to the next if I didn't have it marked. That's why I think posting only one picture of a flower really doesn't tell you much about its overall look. Better to see a variety of photos of the same plant, then you get an idea of it's range and possibly, the most typical coloration.
