Shades: Functional in day and night time

Tired of traditional curtains? I like variety and find the drapes that most houses have a little monotonous. It is nice to spice up the living room or study or hallway with bamboo shades which can function equally well in the daytime and at night to manage the lighting environment in your house. When I was checking the PayLessDecor, I was surprised to find so many different kinds of materials used for shades, I had only thought there were one or two! Was I wrong?
