Mine is open 1 week. I think lighting conditions make an important difference in how the photo turns out. The older photo I had of this flower was taken under a "bluer" light and looked closer to your picture. The light panel I now photograph under has a modestly "redder" color temperature setting. This setting seems to best match what my eye sees when flowers are in mid-morning outdoor sun. The sun at different times of the day has a different spectrum and can make a flower have different color appearance.
