A technique called pointillism builds an image from many small, separate marks of color.
Instead of completely mixing colors on the palette, the artist places different colors next to one another.
When viewed from a suitable distance, the viewer's visual system blends the marks into a more continuous image.
This can make colors appear surprisingly bright and lively.
The technique turns individual dots or short strokes into a larger image.
Up close, you see hundreds of separate marks; step back, and your brain begins to combine them.
