How can a marketer use a package to communicate with consumers?

What will be an ideal response?

A marketer can use a package to communicate brand personality through effective use of colors, words, shapes, and images. In addition to brand identity, the package can provide facts and important consumer tips, as well as warranty information and ways to contact the company. The choice of packaging can make an aesthetic statement about the brand or convey a brand's commitment to social responsibility. For instance, many brands are now marketed in green packaging that is less harmful to the environment than other materials.
