function field_example_field_formatter_view

Implements hook_field_formatter_view().

Two formatters are implemented.

• field_example_simple_text just outputs markup indicating the color that was entered and uses an inline style to set the text color to that value.
• field_example_color_background does the same but also changes the background color of div.region-content.
