A demo type is included. Set INSTALL_DEMO_TYPES = 1 in config.py to enable it. It is disabled by default.

Set OUTPUT_FORMAT in config.py of the field itself to have the color codes in HTMLColor, RGB, HexColor or PILColor. Default is HTMLColor.

Usage:

1. 1. Install as usual in your Products folder
2. 2. Install in your Plone Site with the Quickinstaller tool
3. 3. In your custom Archetype, add::
   from Products.ColorField import ColorWidget, ColorField
4. 4. Use it like a regular field/widget in your Type's Schema. There is an included example.
5. 5. The widget takes a boolean parameter to pick colors on brightness too::
   allow_brightness = True
   

Example::

ColorField('my_color',
        default='#00FFFF',
        output_format='HexColor',
        widget=ColorWidget(
                 label='My color',
                allow_brightness=True)
),
