Blue is the colour of the summer sky and the open sea. It inspires feelings of calm and serenity which can in turn be beneficial to our health - slowing down breathing, reducing feelings of stress and lowering blood pressure. So, choose blues for those rooms where you really want to feel relaxed – living rooms, bedrooms and even bathrooms. Pale blues will feel fresh and reviving, while mid-blues are best for infusing spaces with a tranquil ambience. Darker blues add drama and should be pared with warmer accents and soft textiles so they feel cocooning.
