Here is the sample of Moscow city distant suburb.
As an experiment the dull gray houses were painted to different colours.
From my point of view it’s really amazing isn’t it?
In Russia where is in winter sun is a very rare thing such kind of art might keep the winter depression away. For instance this fall-winter there were no visible sun in Moscow for more than 30 days. Due to this it was reported that a lot of people simply refuse to go to work because of an enormous depressive state they were in.
Maybe such urbanistic art would keep the depression away.
