There are many ways to get the colour red into your home other than painting a wall in that colour.
Or painting different pieces of furniture and even doors in a high gloss red is an easy way to add a bright splash of colour to your room.
A little bit of up cycling is a fun way to add the colour. Painting old chairs and re-upholstering cushions. Or fully re-upholstering chairs like the middle picture above. Another easy way is to paint the inside of mason jars with the colour and use them as vases, storage or candle holders.
Or just buy some simple accessories that you can add to your room.
Red as a colour when in the living room stimulates conversation and in the dining room encourages appetite.
