On the informative media poster "u r what you eat" the colors green, yellow, and red corrosponds with the go, slow and whoa food categories. which best explains the authors use of metaphor with regards to this coloring system?

The coloring system correlates to the metaphor. For example, red often means "stop" or "bad". If a food color is red, then it most likely means that the food is bad. If a food color is green, it will mean that the food is a better food choice.

Hope this helps!
