I would like to ask how the colors that people were in normal days get decided. They must get decided somewhere, somehow, by someone, because the other morning, while waiting for the tram, I was observing the people and I could count many black pullovers, some brown ones, two red ones and two light blue ones, but no other color. Interesting enough, the two red ones were exactly the same red, which is not that easy to find. And the same can be said for the light blue ones. It seems that all people can choose the color of their clothes from a dozen of given ones, and any other color, for a while, disappears.
