How far to push it
Saturation controls how far colours sit from gray. A modest boost makes a photo livelier; too much and skin tones go orange and skies turn radioactive. Negative values drain colour — at −100 you get a full grayscale conversion. For a guaranteed neutral black-and-white, the dedicated Grayscale tool uses perceptual weighting.
FAQ
How do I make colors more vivid?
Enter a positive saturation value and click Apply. It runs in your browser. Keep it moderate to avoid an unnatural look.
Can I fully desaturate to gray?
Yes — set −100. For the cleanest black-and-white, use Grayscale.
