Darker photos are taken in shade, the redder ones in sun. This daylily is a dark red.

Also consider, the light intensity is vastly different in parts of EU than the US. This can cause the colors to be less bold. Years ago, I corresponded with François Verhaert who was living in Belgium at the time. We had both bought a new plant from Pat Stamile called DAKAR. It was a near black for Pat in FL. During bloom season, I posted a picture of Dakar to a pictures group, and François wrote to ask if it really looked like that, as his was this ugly shade of brown. He sent a picture and it didn't look like the same plant. HE had even written the hybridizer with a picture to ask if he got the wrong plant!! So about a week after that, we had several days of unseasonably cool and overcast days. Guess what? The blooms of DAKAR began to look exactly like François 's picture!! I sent him my picture and we agreed, some daylilies are VERY subject to changing color depending on the light and possibly the heat. We concluded it was probably a combination of both. I've seen this happen here when we sometimes get a cool morning or several overcast days in a row! So maybe yours will darken when you get some hot sunny days.

I agree with the replies above. My Vintage Bordeaux and Midnight Raider vary in their darkness. I once thought that people were being tricky with their photos of hems, until I found that taking pictures of a single bloom in the same light even seconds apart often results in very different images. Also I have light coloured hems look lighter or darker than they did a day earlier. Eyes in particular can be very dark or almost invisible. Most of my plants vary heaps in their scape height, flowering time and bloom size. My growing environment here on the east coast of Australia is not a controlled or uniform environment.

There is the possibility that it is not the registered plant that you wanted. So I hope it multiplies so you an try it in different locations in your garden. Bonne chance!
