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.
