This is a challenge.
A two-color version requires and permits movement after taking one's position.
So I don't think it provides useful guidance for this case

Spoiler for here it is anyway

Great puzzle.
Eager to see the solution.

 

 

Spoiler for solution

 

 

I don't see the OP requiring each prisoner to assume his position before the next one enters the room. So why should we be adding such a restriction?

On the other hand, the OP never specified that the place for each row has been marked with like colored chairs, tile, or in any other way. Thus we must not assume that it has.

Given the above, Rainman's method needs just a slight modification.

Spoiler for how about

As for the blindfold, it is kept on until each captive enters the hall to prevent them from seeing the color when it is placed upon their heads and thereafter to hinder them from checking the same in the mirror of the dressing room.

 

 

 

Hasn't Rainman already solved the puzzle? With that small modification I added, so that his solution does not rely on the preset place where to form rows.

I think so, now that Wolfgang clarified that people don't have to take their positions before the next person walks in.
Edit: unless he meant to say "where-ever" instead of "when-ever" in response to my question
But that doesn't generally seem to prevent people from answering.
Maybe Wolfgang will come by to mark it as answered.

To me it seems that 'Entering singly and not changing one's position once taken" are conditions with no effect, if "hanging out" is permitted. What relevance to the solution can that guidance have, other than to prohibit that option? Yet that is what adds the difficulty that I see here.

If language issues have made the point debatable, Wolfgang will have to clarify.

I am at loss about the purpose of "Entering singly". "Not changing one's position once taken" seems to be a reasonable, good, and severe limitation upon those criminals, indeed.

Conversely, if OP requires each conman to take his place in the formation before the next inmate enters the hall, then I cannot imagine what method could possibly exist for the condemned men? After all, the rows would start forming without any knowledge of the color on the forehead of the next culprit to enter...

According to your method(NEWS),seems as if the first prisoner is giving a hint to the others,which is actually not allowed...see the roles in OP

Yes, each one should choose his place where to belong,once he did, he is not allowed to change his mind.(Except the first two ...see OP)

Wolfgang, I think the point that asks for clarification is this:
Must each prisoner wait, outside the room and blindfolded, until previous prisoners have taken their positions?

Yes...thats right....he should wait until the previous prisoner is standing in his raw and took his position.
