Thanks for the many kind comments.
Marie, this is the first bud on my plant, so I can't say how it will be over time. Also, DH took the photo while I was at work, so I haven't seen it in person...yet! DH says the spots were pretty yellow, which gave a peachy appearance. If you look at photos on the IWGS page, there is some variability. Also, I follow Tim on FB and have noticed there is a range in blooms he has photographed. Are you growing it as well?
