COLOURED CHAP (circa 1968) Political correctness is a shallow visitor to our existence - prone to impose false values on us all. Louis Lewis is no subscriber to hypocrisy. He has always called a spade a spade. And more often he has called a spade "a coloured chap." This is no pejorative for the colour-blind Lewis. He sees things in black and white. When it came to painting a portrait of a black man - a notoriously difficult task for any artist (think how few West Indian cricketers turn up in paintings by Goya, Michelangelo or Rembrandt) -Lewis didn't blanch. He simply dipped deep into his pool of inspiration and created a masterpiece. Note the crew-neck sweater in Coleman's mustard yellow. Black power had found its first champion. It was only a matter of time before the barriers dividing the races would tumble like the Walls Of Jericho... And it all started with this startling portrait. Who the "Coloured Chap" was has never been known. Perhaps the Jamaican intern who tackled his stomach blockage at the Middlesex Hospital in 1964. Perhaps the shelf-filler at the Swiss Cottage Tesco's in 1965. Or perhaps he was just the Coloured Everyman who Lewis created to show humankind the way forward. With a visionary artist and spiritual leader one is never sure. One is just grateful to have been touched by his enormous prowess...
