patriotic triple?

hello
after a night of observing faint planetaries
i slewed to 31 cygnus and almost fell out of my chair due to the brightness and color (8" SCT 24 pan). the primary was burnt orange, the secondary (30 cyg) looked white to me and the close 3rd star was pale blue.

decided to snap a few pics with careful color balance and the secondary showed a faint blue halo as well, which makes sense given it's spectral class, A5.

somewhere i read a description of someone coining this as the patriotic triple, but i can't recall where i saw it. does anyone have any more info on this?
