Yes, Pleco fish do change colour. From my experience their colour usually depends on their mood and health. They are normally a dark brown/black colour which means that they are healthy and happy. If their skin starts to go grey or white they are feeling ill and if they go a lighter brown it's usually because they are either stressed or annoyed. There are of course different colour varients of Pleco depending on which type you have, but as general rule of thumb, darker is better. Normally their colour changes mean harmless things, so don't worry unless they are really pale, or their colour change is a symptom of a disease (red stripes, pink inflamation around the eyes, white splotches and other such signs).
