If I want to keep my living room cool in the summer, are light or dark colored curtains better?
I have a large living room window that gets a lot of sun. I want to supplement the existing vertical blinds with curtains to help keep the room cooler. But I'm not sure if a light colored or darker curtain would work better. It seems like a darker curtain would keep the room darker, but would also absorb more energy, while a lighter curtain might reflect more of that energy. Does anyone know the best answer? Thanks!
