General points for beating me at my own theory, extra bonus points for mentioning The Great Gatsby. 

They better still be making people read that in school. Because when Korra is standing on Air Temple Island watching Tenzen stretch his arms out towards the distant green light…

This from listener Eric, just to throw some spice into my current favorite geek theory:

I’m not sure about this Yellow theory because Yellow is usually the colour for the Air Nomads.  To that point, I’ve found it interesting that several citizens of Republic City appear to be in Air Nomad clothing.  However, given that the Air Nomads were nearly wiped out, their traditional colour might very well become symbolic for those against bending.

As far as overall colour palette goes, the golden wash hearkens back to this 1920s “Golden Age” feel.  It reminds me of the opening sequence to The Incredibles.

I think the only safe thing we can say here is: When yellow is used it’s on purpose.
