What do the bold colored lines on heroclix maps stand for?

Question

The only ones that I know for sure is blue for water terrain and green for hindering.

Answer 1

Page 28 of the below listed source:

HeroClix has five types of terrain: clear, hindering, blocking, elevated, and water.

Water terrain has special rules associated with it, and elevated terrain is a special type that modifies other types of terrain. All types of terrain (except clear terrain) are indicated by boundary lines drawn on the map:

• Squares inside the boundary of a green line are hindering terrain.

• Squares inside the boundary of a brown line are blocking terrain.

• Squares inside the boundary of a red line are elevated terrain.

• Squares inside the boundary of a blue line are water terrain.

Three other boundary line colors indicate particular areas on a map and are clear terrain unless indicated otherwise:

• Squares inside the boundary of a purple line are a starting area (see “Prepare the Battlefield,” p. 9).

• Squares inside the boundary of a yellow line are interior spaces on an indoor/outdoor map (see “Indoor/Outdoor Maps,” p. 34).

• Squares inside the boundary of an orange line have special rules, which are explained on the map on which they appear.

Heavy black lines running along the grid lines of the map are walls (see “Walls,” p. 32).
