    """Generate random color hex codes.

    Firstly, it will generate random integer from min_color (0-(255 - lighter_colors_total - 1)) to max_color (0-(255 - lighter_colors_total)).
    The max_color should be less than (255 - lighter_colors_total) because it needs the room to generate lighter colors.

    To generate darker colors, use smaller value for max_color.
    To generate ligher colors, use bigger value for min_color.

    It's recommended to use default values.
    If you want to make change, please make sure what you are doing.

    Secondly, it will generate 'lighter_colors_total' different hex color codes from base color to the lightest color.
    Note that 'lighter_colors_total' includes base color also. It means it will generate 'lighter_colors_total - 1' lighter colors besides base color.

    Parameters:
        min_color - minimum color code. default: 0.
        max_color - maximum color code. default: 254.
        base_colors_total - how many base colors to generate. default: 7.
        lighter_colors_total - how many lighter colors to generate. default: 24.
        plot: True to plot the generated color. Otherwise, False. default: False.

    Retrun:
        Generated random base colors and all lighter colors of each base color.
        The returned value is a two-dimention list. First dimention length is the value of base_colors_total. Second dimention length is lighter_colors_total.
