The old UK colouring (still found in old installations) was black = neutral, red = positive, green = earth. The new colouring is blue = neutral, brown = positive, yellow and green stripes = earth.
With the new colours: on a UK 3 pin plug when facing the contact screws on the back with the cover removed: blue goes to the left contact as there is an 'L' in blue, and Brown is to the right contact as there is an 'R' in brown.
