Pick a favorite blue and yellow double!

What’s your favorite blue and yellow (well, blue and gold, or maybe orange and blue?) Summer/Fall double? We think there are at least four to choose from. Probably the least well known is SHJ 282AC, and for that matter, I’m not sure how many know Gamma Delphini? So, of course, before you vote you should look. I suspect the best known is Albireo (Beta Cygni) with Almach *Gamma Andromedae” not far behind.  If you would like a little more informaiton on star color before making your choice, go here. And, of course, feel free to explain your choice or suggest another pair visible in the summer/fall sky by using the comment section on this post.
