Why are random creeps red?

Every creep I put in map using a random unit, are given the team color red in the game, instead of the black that neutral hostile usually have. They do show correctly black in the editor, but they are red in the game.

I thought this was simply a game bug and I was about to report it to blizzard when I took a look at the FFA ladder map (6)Jungle Fever.w3x . This map uses random creeps the same way I do, but they correctly show black team color in the game. As an example of what I am saying, you can compare Jungle Fever and Tranquil Paths, they both use random creeps, but they are red in Tranquil Paths and black in Jungle Fever.

I tried to compare whatever I could about this two maps in the editor but I couldn't find what was causing that difference. Then I also looked inside their .j files, but their random creeps definitions and unit creation triggers seems much like the same. I noticed that they both use a:
call SetUnitColor( u, ConvertPlayerColor(0) )

in unit creation, I am not sure of what does ConvertPlayerColor() do. Zero should be red, but jungle fever uses this same function and the creeps displays black.

How do I make the my random creeps have a black team color too?

You can force all the creeps to be team color black in the unit editor.

I also noticed that they seem to be red no matter what you do.
You can trigger the teamcolor of Neutral Hostile to black at the beginning of your map.

Sorry I forgot to say I want a melee map, neither I want to edit units or triggers.

Blizzard made this in Jungle Fever, I just want to know how.

Maybe you could copy and past the units into your map?

It's a known bug, it random creeps use player 1 (default to be red)'s color. Apparently it will be fixed in the next patch. Along with a million other things that we are hoping for.

copy/paste to my map does not work, but I do can copy/paste from my map to jungle fever, but I want my map not blizzard's

if it is a bug indeed, then blizzard somehow figured a way through it. Check (6)Jungle Fever.w3x in the Frozen Throne folder you will see black random creeps. Any clue how did they do that?

This bug has been there since the original roc version, Tranquil Paths has this bug, so blizzard knew it and still have not fixed it. Do you know something that I don't to say that "apparantly it will be fixed in next patch" ??

Its a bug. There were much more important bugs before this ones, so Blizzard is fixing them first. It doesn't really affect gameplay. Sometimes it happens, sometimes it doesn't. Its never happened to me.
