Yep, Daylily (Hemerocallis 'Regal Heir') looks to be purple in color. I wonder if the labels got mixed up ... happens all the time with plants at big box stores. Yous looks more like Daylily (Hemerocallis 'Regal Air') but I know nothing about daylilies and I'm really bad about comparing photos for ID so it's just a guess on my part
