点彩画派是一种用超粗的彩点堆砌，创造整体形象的油画绘画方法，创始人是秀拉和希涅克，此名称是来源于1880年代的艺术批评家们对他们绘画的讽刺，现在则成为一个正式名称。点彩画派又称新印象主义，也叫分色主义，其主要代表人物除了创始人外，还包括毕沙罗等人。

点彩画派的画家反对在画板上调色的绘画方法，他们只用四原色来作画，用色点堆砌，如同电视机显像的原理一样，利用人类视网膜分辨率低的特性，使人感觉出一个整体形象。

点彩画派的作画方法是19世纪科技发展的一种反映，也是美术的一种新尝试，对后来电视和显示屏的发明也是一种启示。点彩画派对20世纪的音乐发展也有一定的影响，奥地利音乐家韦伯恩就应用点彩的方式作曲。

Pointillism /ˈpɔɪntᵻlɪzəm/ is a technique of painting in which small, distinct dots of color are applied in patterns to form an image. Georges Seurat and Paul Signac developed the technique in 1886, branching from Impressionism. The term "Pointillism" was first coined by art critics in the late 1880s to ridicule the works of these artists, and is now used without its earlier mocking connotation. The movement Seurat began with this technique is known as Neo-Impressionism. The Divisionists, too, used a similar technique of patterns to form images, though with larger cube-like brushstrokes.
