Some colors are obvious, but some are not (at least to me). For example, what does it mean when an area is shaded pink?

If I search by postal code, the area for that postal code has a pink outline, when zooming back, the whole section is covered in pink. Same thing for a City, or a county , state, or even country.
Some of the legend info varies on map type and region.
