"Those who know what I dont know refer to the yellow red and green"
yellow red and green are the three colours of a standard american directional traffic lamp.
If "those who know" live where you are just passing thru, they will probably guide you to your destination by street lamps, for example their directions to you may say "go straight until you see a set of lights, take a left, you'll see another set of lights, keep straight, it'll be on your right"
"lost in the legend"
would be trying to decipher the legend on a map...or perhaps being fascinated with a local legend of a place you are visiting...
