class ColorButtonRow(Adw.ActionRow):
        Initializes a ColorButtonRow widget with a color button and optional title and subtitle.
        Parameters:
            title (str, optional): The title to display in the row.
            subtitle (str, optional): The subtitle to display below the title.
            default_color (tuple[int, int, int, int], optional): The default color to set for the color button in
                                                                RGBA format (default is black with full opacity).
        Description:
            This constructor creates a new ColorButtonRow widget. It sets up a Gtk.ColorButton for selecting
            a color and assigns it to the row. The initial color is set based on the provided `default_color`
            tuple, which represents the color in RGBA format (each value ranges from 0 to 255).
            Additionally, the color button is connected to the `color-set` signal, which triggers the `_on_color_changed`
            method when the color is modified. The color is stored internally as a tuple of integers representing
            the RGBA values.
            The row is set up with a title and subtitle if provided.
