## Lightness/darkness adjustments

How to lighten/darken

```js
let color = new Color("hsl(20, 100%, 30%)");

// HSL lightness adjustment
let lighter = color.clone();
lighter.hsl.lightness *= 1.5;
lighter;

// LCH lightness adjustment
let lighter2 = color.clone();
lighter2.lch.lightness *= 1.5;
lighter2;

// Tint
color.mix(new Color("white"), .5, {space: "hsl"});
```

More HSL ugliness:

```js
let color1 = new Color("hsl(60, 100%, 50%)");
let color2 = new Color("hsl(230, 100%, 50%)");

let lighter1 = color1.clone();
let lighter2 = color2.clone();

lighter1.hsl.lightness = 70;
lighter1;

lighter2.hsl.lightness = 70;
lighter2;

lighter1.deltaE(color1, "2000");
lighter2.deltaE(color2, "2000");
```
