impressionists

Claude Monet and Auguste Renoir were impressionists. Édouard Manet belonged to the same circle of friends and colleagues, but only for a short period painted in an impressionist way.

some other impressionists were Manet and Renoir, then there was Vincent vanGogh but he was not an impressionist artist, he loved big bright colours

He worked with the impressionists (Monet, Renoir, Sisley, Morisot, Cassatt), Manet, Suzanne Valadon.

True. Quite true. Manet was actually a pioneering Modernist. He is lumped together with the impressionists purely as a matter of the period in which he lived and painted. It's like calling someone "classic rock," just because they recorded in the 1970s.
