If you choose to incorporate a red rug in your space, you can match the color with other reds in your decor, or you can use it to complement colors like brown, orange or yellow. Red rugs come in a variety of shades, from bright fire engine red to deep autumnal auburn, so choose a tone that fits your style.
Also, consider the aesthetic of a space when choosing a rug. Red rugs can be traditional with floral, quatrefoil or Moroccan patterns. They can also be more contemporary, featuring geometric designs or sleek, minimalistic patterns.
Use a red rug in your space to warm it up, since red is such a warm color, and enjoy the softness it adds to your floor.
