    This is a class for clickable, single colored paint tiles in the GUI of the pygame application.
      
    Attributes:
        x (int): X-position of the tile.
        y (int): Y-position of the tile.
        width (int): Width of the tile.
        height (int): Height of the tile.
        color (tuple): Background color of the tile in RGB format.
        image (pygame.Surface): Pygame Surface object to render tile in GUI.
        rect (pygame.Rect): Pygame Rect object for rendering and collision detection.
        clicked (bool): Bool to represent whether or not the tile is clicked.

    Methods:
        draw(self, surface, *, border=False)
            Draws the tile on the pygame surface and returns True if button is clicked. 
            Also draws a black border around the tile if border parameter is True.
