The saturation of a color is its degree of richness, purity, or grayness. Other commonly used terms are intensity, and chroma, which is technically a different attribute, but to simplify things we will treat it the same. For example, cadmium orange is a high saturation color, and burnt sienna is a low saturation color.
Both colors are the same hue (orange).
Similarly, yellow ochre is less saturated than cadmium yellow. Any given hue reaches its highest saturation at different values. Understanding saturation is an essential skill for creating an interesting color design.
To add interest to your paintings, use a variety of saturation levels. For example in the painting above I used saturated colors in the lit part of the temple, and grayed colors in the buildings at dusk.
Munsell notation — saturation
On the left, you can see how red goes from high to low saturation in art. In the Munsell system on the right, the saturation increases from the center pole moving outwards. The Munsell notation goes from 0 (neutral) to 12 for the most saturated tube colors. It is a useful way to denote color saturation in art.
