# Saturate
Color saturation correction
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**

## 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 human visual system color intensity perception, you should use the **gray** parameter instead.
{% endhint %}
