An opaque color curtain typically refers to a curtain that is made from a fabric that doesn't allow light to pass through, providing full privacy and blocking sunlight. These curtains can come in various colors and styles, with solid hues, patterns, or textures. Opaque curtains are usually made from heavier fabrics such as velvet, thick cotton, polyester blends, or blackout materials. Common color options for opaque curtains can include neutral tones like beige, grey, white, or black, as well as bold shades like navy blue, burgundy, or deep green.
