```cs
public sealed class Modifier.Contrast : Modifier
```

Stretches lightness away from mid-grey, or squeezes it towards mid-grey for negative percentages. Light colours get lighter and dark ones darker, so the order of a set of shades is kept; at -100% every colour has the same lightness. Chroma is left alone, that is what [Modifier.Saturation](https://developer.rhino3d.com/api/gh2/type/grasshopper2.ui.skinning.modifier.saturation.md) is for.
