A question about colors

[PeteVS]

I've attached a couple of pictures and I'm wondering about the colors.
First is the dust jacket from Henry's Lady showing what I assume to be a '29 Phaeton. I like the color, sort of a khaki and orange wheels.
Second is a page from the MAFCA Paint and finish guide showing that a '29 Phaeton with orange wheels would be painted Rose Beige body color with Seal Brown belt moulding color.
Third, from the same book, is the color sample page showing "Rose Beige" but this Rose Beige looks nothing like the car in the first photo.
So, is the book cover car painted an "inappropriate" color? Or, is the page showing the color combination wrong? Or, is the color sample wrong? I had bought this book several years ago and remarked that most of the "dark" colors looked way too dark. I managed to lose that copy and recently bought this new copy and it still appears that those dark colors are still way too dark.
Thanks for any explanation you can offer!!
