Refer to value in field in body UPDATE: Although the answers below were correct, I ended up resolving the issue by editing the stylesheet to refer to those specific locations.



If I create a custom field and set it to hidden, is there any way I can call the values from those specific fields in the body? 

For example if a field called color in an article is set to red, is there any way I can make the background of a div red.
Try what I suggested here: Getting a field&#39;s value from an entity

Replace field_get_items('entityform', $entityform, 'field_myfieldname') 

with 

field_get_items('node', $node, 'field_myfieldname')
