colour thread

Last midnight i was at a near petrol station, on my way back there was a black dressed man with short hair, shaved and grown, maybe in his 40ies, he had his eyes closed and and his forehead frown when walking in my direction. He was holding this expression to present it.
The last time before when i was outside i was at the cheap supermarket, there was a black dressed man, maybe in his 30ies, with bald head.
Both didn't look especially neither like right extremists, nor lefties, don't know what these skinheads were like.
In the morning of this 7th an older black dressed man came towards me, just when i cycled down the street here, with his right hand he hurried touched his cheek, in his left hand he was holding a sheet of paper, the way that it would better fit to a situation in an office.
Maybe it was a police "theme".
Also on the 7th, when leaving the house and opening the door, in that moment a overwighted man dressed in a black baseball-jacket with black sleeves, black trousers, also black boots as i remember, passed in front of me.
The day before at a streetcrossing there was a black man with a black beret, on a bicycle, he had a somewhat nerved or angry expression, when i came closer he looked at me as if he would expect something.
On the other side of the street there was a black dressed man, a lefty, who was watching me, but he did not want that i know that he was doing so.
This was very unusual behavior, because if people are watching me they usually want me to know this.
Also that day there was another black dressed lefty (maybe in his 40s), on a bicycle, he was looking in my face, this had a meaning to him, maybe he was curious, this was immediatly after the third person who made a sniffing noise(wich i had already described, on the 6th febr.).

In 2000 it started with the colours, there were smaller groups of people who wore the same colour. Nearly all colours were used during the year, with red-tones, from orange to purple, dominating.
In 2001 then orange was popular all the year, the theme fits somehow to the support from martial artists, and in 2002 it was blue.
While orange symbolizes buddhism, blue seems to do also, kind of neo-buddhism.
In 2001 there was also a short but intense green phase, that did not last longer than two weeks. The green seemed to be muslim and where opposed to the orange, i think they both claimed that i was the leader of the other, most of them showed up on one of the bigger streets here, it was a cocky catwalk.
At the end of 2002 red was also popular.
Sometimes colours are still used, mostly orange and blue, but far less than during these years. It can also be combined with the basic-sign, or whatever.

From mid of 2002 to mid 2004 there have many black people shown up, it started abruptly, and then decreased in mid 2004, but the structures still exist.
Nearly all were black males with very dark skin, but no older or small, overweighted, teenagers, no big glasses, it seems it was a kind of draft
(otherwisw there are people of any age, male and female).
The first ones were all bald.
They did not wear blue colour, nor did they use the basic sign.
Before 2002 there have been black men only once, two men on bicyles, they said something like "dead cattle", the next persons who came towards me were two long-haired blonde women, looking both much the same, laughing too childish for their age. This was in 99, i think.
