Seurat's optical mixture created greater luminosity.

Explanation:

    Still in impressionism, the artists were constantly searching for new painting methods and after new discoveries regarding color and light, so it turned out that it was not necessary to mix the colors in the palette or the canvas itself, we realized that our vision has something called “optical mixture” which is nothing more than the association by the vision of mixing two colors together to form the third color, so many artists begin to compose their work in a different way, the so-called pointillism working with the meaning. The human eye, seeing the work from a distance, the human eye sees the colors mixed, but approaching realizes that are numerous points of color that gives us the sensation of mixing.
