We celebrate our first anniversary with a live audience special where we talk all about colour and interior design.

In the company of colour and design consultant, Karen Haller, the author of 'The Little Book of Colour' and Marianne Shillingford, Creative Director of Dulux, Jeff, Susie and our audience of designers learn about colour psychology and its impact on interior design.

We ask how colour works and learn about its innate power to change human behaviour, happiness and well-being. We then discover how interior designers can harness the positive virtues of colour in their work.

Karen and Marianne also answer questions as part of a lively discussion that's packed with insight and intelligence.

Recorded at the fabulous Roca London Gallery in Chelsea Harbour.
