Changing color on scroll

lax.js 2.0.3

Describe the bug
I'd like to create a background color changing effect on scroll, but can't figure out where to start. Do you have any clue for me please ? Do I have to write a custom css function callback in order to compute the correct color depending on the scroll possition ?

Code

    lax.addElements(
      'body',
      {
        scrollY: {
          "background-color": [
            [0, 100],
            ['#FFFFFF', '#000000'],
          ]
        }
      }
    );

Only specific CSS properties are possible, see https://github.com/alexfoxy/lax.js#css-properties

I suggest trying : hue-rotate or brightness
