# Saturate
To adjust the color saturation, you can use the **saturate=X** filter and set the desired adjustment value (`X= -100..100`). Negative values will decrease color saturation while positive ones will increase it.
**saturate=X**
## Examples
| Preview | Syntax |
| -------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
|  | Original image:
/samples.scaleflex.com/frog.png?w=400
|
|  | Increased saturation:
/samples.scaleflex.com/frog.png?w=400&saturate=35
|
## Desaturate
Using **saturate=-100** will remove all color information and convert the image to grayscale.
{% hint style="info" %}
Please keep in mind that desaturating an image just discards all color information. If you prefer to create a grayscale image while taking into account the human visual system's color perception, you should use the **gray** parameter instead.
{% endhint %}
