### Example Usage

Source: https://github.com/halostatue/color/blob/main/README.md

This example demonstrates how to make a given RGB color lighter by adjusting its lightness component in the CIE LAB color space while keeping other components intact, and then converting it back to RGB.

```ruby
c = Color::RGB.from_values(r, g, b).to_lab

if (t = c.l / 50.0) < 1
  c.l = 50 * ((1.0 - t) * Math.sqrt(t) + t**2)
end

c.to_rgb
```
