Yes this book said it was a Blue Fawn and although the picture is different then one in the book its the exact same color. There are a couple other pictures like that and show a same colored dwarf wich the is called a blue campbells.
I cant see that they are wrong, I mean the name suites the color perfectlly. although I dont know much about color genetics, Afishcalledwanda doesnt look blue at all lol. If this isnt a Blue color then I dont know what is!
HERE is a link to one site that shows the colors, the only there that looks close to the blue fawn is the Opal.. Hmm but it does seem funny this site shows a blue fawn wich looks more tan with a blusish dusty undertone and they simply call the blue campbells "blue" Maybe this book did make a typo on that one picture.
Oh who knows lol
