You won’t be able to switch colour on the pseudo elements (if that was the idea)…

Here’s some generic code, I’d probably choose the filter function for it:

$('button').click(function() {

  if ($(this).index() == 1) {

    $('.line').filter(function() {

      if ($(this).css('background-color') == 'rgb(241, 74, 255)') return this;
    })
    .css('background-color', 'black');
  }
});

Edit – actually, you can with a bit of CSS trickery:
