The farbtastic instructions are to use something like the following in
the jQuery(document).ready(function():
jQuery('#picker').farbtastic('#color_value');
where 'picker' is the id of a DIV that will hold the color picker,
so I just added it in the third column of the form via:
col3={ 'value':DIV(_id='picker') }
so it will appear next to the input text field with id 'color_value',
where 'color' is the table name and 'value' is the field name.
However, they forgot to mention that it will only update the field's
value if it already has one, so I just initialize it with:
db.color.value.default='#ffffff'
Happy coloring!
