class Colors:
    """A class that defines the color scheme for a theme as well as
    provides several static methods for manipulating colors.

    A `Colors` object is attached to a `ThemeDefinition` and can also
    be accessed through the `Style.colors` property for the
    current theme.

    Examples:

        ```python
        style = Style()

        # dot-notation
        style.colors.primary

        # get method
        style.colors.get('primary')
        ```

        This class is an iterator, so you can iterate over the main
        style color labels (primary, secondary, success, info, warning,
        danger):

        ```python
        for color_label in style.colors:
            color = style.colors.get(color_label)
            print(color_label, color)
        ```

        If, for some reason, you need to iterate over all theme color
        labels, then you can use the `Colors.label_iter` method. This
        will include all theme colors.

        ```python
        for color_label in style.colors.label_iter():
            color = Colors.get(color_label)
            print(color_label, color)
        ```

        If you want to adjust the hsv values of an existing color by a
        specific percentage (delta), you can use the `Colors.update_hsv`
        method, which is static. In the example below, the "value delta"
        or `vd` is increased by 15%, which will lighten the color:

        ```python
        Colors.update_hsv("#9954bb", vd=0.15)
        ```
