It can be a brave move to bring bright colours in to your home, however the risk can pay off as the bright colours can bring joy and happiness. We inherited a bright orange sofa when we moved in to our current house. To be honest, at first, I did not like it AT ALL. However, we painted the walls grey and have metallic accessories and now I actually quite like it.
It is amazing how much colour can influence mood. If you are not quite ready to buy a bright coloured sofa, try bright accent colours first. Go on, try it!
