Is it utopian to use colour to improve our lifestyles and feel more at home? Today, we are very aware of the history of colour, the subtleties of how it is made, its origins, diverse uses and benefits for people. But do we really understand it?

We know how much these colours are essential to our lives. So how can we use colour to improve our lifestyles and feel more at home? Why should we bring it into our interiors and why do we need it in our lives?
