+   * Checks the contrast between two colors. This method returns a boolean
+   * value to indicate if the two color has enough contrast. `true` means that
+   * the colors has enough contrast to be used as background color and body
+   * text color. `false` means there is not enough contrast.
+   *
+   * A second argument can be passed to the method, `options` , which defines
+   * the algorithm to be used. The algorithms currently supported are
+   * WCAG 2.1 (`'WCAG21'`) or APCA (`'APCA'`). The default is WCAG 2.1. If a
+   * value of `'all'` is passed to the `options` argument, an object containing
+   * more details is returned. The details object will include the calculated
+   * contrast value of the colors and different passing criteria.
+   *
+   * For more details about color contrast, you can checkout this page from
+   * color.js. The WebAIM color contrast checker is a good tool to check out as
+   * well.
