When you purchase these,  pick up a can of spray paint that coordinates with the color of the shade. Heres why......the top of the shade canister that holds the shade,  the part that clips onto the brackets is white.  Example....I ordered the Taupe (brown) shades and Im placing them on brown wood doors. The WHITE canister stands out like a shore thumb. I spray painted it brown and it now blends nicely. 
Not certain why they dont paint the color of the canister the same color as the shade but maybe theyll read this and fix the problem. As far as the actual shade goes,  its wonderful!
