Here are some ideas for the titles and captions font and color for your documentary:
Titles:
- Use different colored food items (chips, carrots, apples etc) to spell out the title
- Have the title being "written" by hands mixing/preparing food
- Animate the title being "consumed" - like letters being eaten by a burger or cake
Captions:
- Use a simple sans serif font like Arial for clarity
- Make the font size decrease to show hierarchy
- Use different shades of colors associated with the episode topics
- Red for sexuality/passion
- Green for nature/growth for the ideology episode
- Brown/orange for capitalism episode
