Well than you have no color saved inside Gang[gangid][GangColor] if it is black

You could simply test the code with that

pawn Код:

// setting red into GangColor, full alpha
Gang[gangid][GangColor] = 0xFF0000FF; // RED
// GangZone should be red transparent
GangZoneShowForAll(GangZone[zoneid][ZoneHolder], ((Gang[gangid][GangColor] & ~0xFF) | 0x50));

Guess something is wrong with your GangColor code
