His technique is called "broken color" and uses overlapping layers of scumbled or dashed clean colors. The colors, often complements, are placed together to visually blend into a new color as the viewer observes the image. The technique creates a lively, flickering effect.
Monet used his knowledge of color with painting techniques to capture a brief moment in time- the "impression" of what you see before you. He often worked outdoors, painting for a short time before changing canvases for the next "moment". After several days or weeks of working in the same location for the same brief moment, he was able to develop a completed image.
