One way of avoiding subtractive colors when using pigments is pointillism, originated about 1885 by the French painter Georges Seurat. Small dots of saturated color paints are placed next to each other. When viewed from a distance far enough away so that the dots cannot be distinguished, the result is the additive color of the two pigments. In this way, green and violet dots would give white, and not the black that results when the pigments are mixed; the advantage is that much brighter colors can be achieved.

原来是这样！好聪明！就跟显示屏的原理一样！我还以为 pigment 只能 subtractive mix！
我查到 Pointillism 是 Georges Seurat 和 Paul Signac develop 的，正想说难怪我今天在画廊里见到的某幅画那么亮，结果一看就是 Paul Signac 画的！好巧啊啊啊
