Some September sky blue cushions and blankets could make it stay. I for my part got lots of retro fabric stacked up and ready. - Photo from the Danish magazine Boligliv. Always good for colourful interior settings.
Paint an old cupboard blue and go for some September blue home decor could be another option. - Photo from the always inspiring Apartmenttherapy. The retro tablecloth and flower pot is from my shop and the Kähler vase in the middle is my own.
