# Saturation
> Increase or decrease color intensity with the e_saturation token.
Saturation controls how intense the colors in an image are. Raise it for vibrant, punchy color; lower it for a muted, desaturated look.
Add the `e_saturation` token to the transform segment of any delivery URL:
```bash theme={null}
https://assets.autorender.io/LOKVTtKVGb/e_saturation:30/docs/example/porsche.jpg
```
## How does it work?
`e_saturation:{level}` takes a level from **−100 to 100**. Negative values drain color toward grayscale, positive values intensify it, and `0` leaves the image unchanged. At **−100** the image is fully grayscale.
Compare levels:
```bash theme={null}
https://assets.autorender.io/LOKVTtKVGb/docs/example/porsche.jpg
```
```bash theme={null}
https://assets.autorender.io/LOKVTtKVGb/e_saturation:30/docs/example/porsche.jpg
```
```bash theme={null}
https://assets.autorender.io/LOKVTtKVGb/e_saturation:-50/docs/example/porsche.jpg
```
## When to use it
* Make colorful photos more vivid and eye-catching.
* Pull colors back for a subtle, muted aesthetic.
* Enhance product colors so they read accurately.
* Create vintage or washed-out looks with negative levels.
## How do you combine it with other effects?
Chain saturation with contrast and brightness in one comma-separated segment. We recommend levels between **20 and 40**, because higher levels push skin tones and reds toward looking artificial (e.g. `e_saturation:25`).
```bash theme={null}
https://assets.autorender.io/LOKVTtKVGb/e_saturation:25,e_contrast:20,e_brightness:10/docs/example/porsche.jpg
```
## Next steps
Remove color entirely with `e_grayscale`.
Widen or narrow the gap between light and dark areas with `e_contrast`.
Lighten or darken the whole frame with `e_brightness`.
