No, my paintings are not that colorful.
BUT, i like how it is painted anyway. Seurat uses an enormous amount a short brushstrokes or dots to create this simple looking piece. He painted it with a broken color technique. He puts blue and yellow dots together and they will visually mix to a green (if seen from distance).
You could replicate this effect by grabbing blue and yellow paint with your brush and without mixing them on the palette put the stroke directly on the canvas. The will mix a bit, but the will also maintain their original character.
It is one of my favourite painting techniques and worth trying out.
