Natural woven shades come in gray and white tones now. Usually the back side looks ok but would double check.
Roman shade has a backside that won’t look good from hallway
Like what you have upstairs. Just different color.
Roman shades are nice but you need both sides to look good. Usually one side is a backside
Can change glass to frosted
Shutters always look great from both sides
Blinds like you have. Look good from both sides
