I LOVE this color combination.
I think it's clean and fresh looking, but also extremely cozy. Gray and saffron are really different colors (in my mind), but look awesome together. I would love to implement that kind of color scheme in my own home. But, when I try to figure out a wall color that would match them, I go blank. Would you paint walls gray? Would you paint them saffron? Or would you paint them an entirely different color? How would you coordinate this bedding with a room??
*If you are not familiar with Remodelista, it is a pretty amazing sourcebook for designers and non-designers alike. It, in fact, is "the sourcebook for the considered home," which, incidentally, is exactly what I want my home to be. Their iPhone app gives daily items that sometimes make me go weak at the knees.
