Yellow is fake gold; it's veneer and show rather than substance. We see that with the yellow cocktail music at Gatsby's party (1) and the two girls in twin yellow dresses who aren't as alluring as the golden Jordan (3.15).
I think a moderate income is income above the median for famlies in your county, but not more than 25% of the median income.

What is 'Household Income'. Household income is the combined gross income of all the members of a household who are 15 years or older. Individuals do not have to be related in any way to be considered members of the same household. Household income is an important risk measure used by lenders for underwriting loans, as well as a useful economic indicator of an area's standard of living.
