Maria, even the Fauvists had variation in their particular manners of painting and could easily be recognized one from another. I personally see no reason one can't adopt the "program" with enough research to further the studies of a particular way of seeing and painting...but take the case of Impressionism. Creating a painting that has the appearance of Impressionism while sitting in one's comfortable, dial-a-temperature, cozy studio with fake sunlight bulbs looking at a photograph (and then of some place one has never been - even worse) is not being an "Impressionist" by any stretch of the imagination. It is an carnival act creating bogus goods that only look like Impressionism to the unsophisticated eye.
Impressionism is done outside in real life looking at real things in real time in real weather looking deeply at the color games as sunlight interacts with various substances.
