Georges Seurat (1859–1891) was impressed by these new theories, and he not often used black pigments in his extremely methodical work. In A Sunday on La Grande Jatte, he used dots of color, together with Ultramarine Blue and Pink Lake, for the black areas of the portray. From afar they seem black, however while you search for shut you possibly can see that they’re alive with color.
