Remembering some of the mad trips I made with my mother to the Far East, I am struck by countless instances where colour becomes a way to express cultural identity and spiritual significance. The Holi Festival in India signifies the arrival of Spring and the triumph of good over evil. It is where people come together armed with an array of coloured powders and water and where strangers drench each other in an explosion of vibrant colours! More recently on a trip to Mexico City last spring you cannot get away from the kaleidoscope of colours - whether in Luis Barragan’s houses, the markets, the traditional dress or at its most simple the food. Even the Day of Dead, a tribute to dead ancestors, is characterised by a riot of colour and elaborate altars full of “ofrendas” made of marigold flowers, painted skulls and so much more.
