Strictly speaking, russet is reddish-brown, but most lists of russet roses also include any beige or tan-colored rose. I've gone through several lists of russet roses and the following pictures are the russets I have in my garden.
Some are difficult to photograph. I'm not a photographer, so I can't give you a technical explanation, but it has something to do with a blue overlay on an orange rose. I guess it takes color adjustments to get the right shade. I've found the color of some to be nearly impossible to capture on film, so there are no photos of Cafe Ole, Cinco de Mayo, Cinnamon Girl, Coffee Bean, Hot Chocolate, and some others here. Maybe someone else has good pictures of them, but my camera refuses to capture them realistically.
This is Amberlight, a 1961 LeGrice floribunda with just enough beige to be included on some lists of russet roses.
