Funny, i JUST had a shipyard pumpkin head ale on saturday. I didn't find it particularly light colored for a pumpkin beer...it was the same color in fact as the Buffalo Bill's Pumpkin Ale I had saturday (can you tell I was tasting various pumpkin brews?)
I'm sure there are darker examples out there. the brew I made last year was based on the number 1 recipe in the database here. Its either Yoopers or Yuri's recipe...I can't remember which. But you wanna read that thread for sure!
and I did my spice addition in secondary, steeped as a tea then cooled and added to the carboy.
