# Saturation Augmentation

Randomly adjust color vibrancy in images to make your model resilient to saturation differences.

Randomly adjust the vibrancy of the colors in the images.

* Percent: The percentage by which color saturation is randomly increased or decreased. Positive values make colors more vivid, negative values make them more muted.
