Neoimpressionism \Ne`o*im*pres"sion*ism\
   (n[=e]`[-o]*[i^]m*pr[e^]sh"[u^]n*[i^]z'm), n. (Painting)
   A theory or practice which is a further development, on more
   rigorously scientific lines, of the theory and practice of
   Impressionism, originated by George Seurat (1859-91), and
   carried on by Paul Signac (1863- -) and others. Its method is
   marked by the laying of pure primary colors in minute dots
   upon a white ground, any given line being produced by a
   variation in the proportionate quantity of the primary colors
   employed. This method is also known as {Pointillism}
   (stippling).
