ELI5: Why do businesses in lower income areas use brighter colored signs with more information than businesses in higher income areas?

This also seems to be present in packaging for products, the lower end the product, the more that is written on the package and the brighter the colors.

I don't know about product packaging, but store signage is regulated by the local government.  It's very common in affluent communities to have very strict rules, and "drab coloring" using dark blues, greens, and browns is a requirement in the wealthy planned community near me.
