Artificial Intelligence (AI) colouring programmes are all the rage at the moment, and can be quite successful when it comes to adding yellow sands and blue skies to an old snap of Blackpool, or even a bit of colour to the cheeks of your Great Aunt Maude. The real test, however, is asking the AI wizard to colourise something a little more gritty, and a little less likely to feature in the coded algorithms of blue dresses and green leaves. As a test - and for want of something better to do whilst being half bored to death by a tedious goal-less FA Cup tie on the telly - I subjected one of my old photographs of Dean Clough to Deep Blue and his/her mates. The result is some mucky looking steam, enough browns to kit out a small army, and a few greys with smiley faces. On the whole, not bad! (Update: there were two goals in the last five minutes of extra time).
