You must use color codes.

pawn Код:

GangZoneShowForPlayer(playerid, zone, color);

As you can see, 65477, -65332, -2147418167 are not color codes.

EDIT: Example:

pawn Код:

GangZoneShowForPlayer(playerid, Ballas, 0x00FF00AA);

Will show a gang zone called "Ballas" as the color GREEN (0x00FF00AA).
