Toni, I love Autumn Sunset so much that I already have four of them, and I'm sure I'll buy it again whenever I see it in bloom at a nursery. It's pretty much irresistible.
I don't know that I'd call it yellow, though. It's more of an apricot blend, with lots of yellow, but also with beige, orange, and even pink. It doesn't get very tall. I think 8 feet is as tall as it has climbed in my garden.
Did you see the photos in our database? You can see that most of them aren't very yellow.
