This may be an unresolvable conflict. Dahlia World lists this as a blend of red and orange, but I was able to find a European supplier (name Procvetok, and website in a language that uses a Cyrillic alphabet, so largely unreadable by me) with a picture that resembles yours. I can't vouch for the absolute veracity of the info in Dahlia World's list, so I guess we'll just have to let things rest as they are.
Since all dahlias are beautiful, regardless of their name or provenance, no real losers here.
