If only it were as simple to change your interior decoration as it is your clothes. If it were, exploring the depths of Indigo blues would be high on my decorating agenda this summer. The trend for Indigo blues has been simmering away for a few years in the UK. For holiday homes in the Hamptons, Scandinavia and in parts of the Greek Islands, it never really disappears. Blues are sometimes accused of being cold, but there is nothing icy or ‘blue’ about Indigo. It is velvety warm at its deepest hue and can be as smart, boho or as classically pretty as you wish it to be.
