Does climate affect lily color?

Albany, ME(Zone 4b)

My pink Algarve lilies are sometimes a lovely light shell pink. Sometimes it is so dark as to be a light maroon. This year they are all quite dark and we have had a very cool spring and summer. It has rarely reached 80 degrees. Is it possible that the color is lighter when it's hotter and darker when it's cooler?

This is what I was told and find to be quite true. I think it relates to night temperatures especially, but you'd have to check on that.

Thanks, Echoes.

Now that it's at the end of the lily season I saw that my Algarve also lightened up as they were dying. But I'm glad to get confirmation about my suspicions about temperature.
