From what I understand, Summer was the darkest shade in Stila's Summer Shades e/s trio, but it's now available as an e/s pan single. I love this. It is by far my favorite bronze eye shadow. It's a shimmery brownish bronze with a hint of rust. It is just a hint of rust though; otherwise, I couldn't wear this shade. I love to wear it in the crease with Stila Wheat, MAC Grain, or MAC Ricepaper as an allover shade and dark bronze-y brown eyeliner. While Summer isn't a unique shade, it is really beautiful and a must-have if you are into bronzes. The texture is soft and smooth. It blends effortlessly and lasts the day on my super oily lids with one of my trusty MAC Paints as an e/s base.
