What color roller shades work best at reducing sunlight?

If you're looking to maximize your roller shades' ability to block out light while matching your interior decor, look for darker colors, dark green, grey, burgundy, and brown. Black, of course, provides the ultimate in light blocking functionality, and this color is perfect for home theaters, man caves, and home offices. Anything labeled as blackout on our website has fabric that is 100% opaque, not allowing any light to penetrate the fabric itself. There will still be residual light around the edges of any roller shade. For best coverage, most people mount the roller shades outside the window. Roller shades are ordered using the width at the top only. The fabric will be 7/8" to 1 1/2" less than the ordered width. We recommend ordering a roller shade at least 3" wider than the window opening when mount the shade outside the window opening.
