I saw the video : http://tinyurl.com/2dthj5l Impressionism/Post-Impressionism Lecture
This video describes the differences and sameness between impressionism and post-impressionism. Impressionism is about light and color; impressionists draw paintings with color theory, they put colors on the palette, and mix colors, it's called optical mixing. They draw paintings by learning directly from nature. They draw paintings with vivid colors. The painters paint the subject over and over in order to catch the exact color. And the post-impressionists use impressionist techniques but they want to take the style to a whole new level. They paint with more patience, more expression, and use color to communicate about the world; they were searching a deeper meaning in the art.
In my opinion, I can't tell the differences between impressionism and post-impressionism, because I don't have any art sense. But according to Monet's paintings, he used several colors and mixes them, so the paintings are filled with the variation of colors and light; his paintings make the scenery more colorful. In order to create colorful scenery, the painters use colors to cover the original colors.
