In the University I studied the #building was early work of a later famous #architect in the style of #brutalism As gray walls are not really motivating the #students wanted to paint the walls and and a professor paid the paint.
There was a lot of trouble and at the end, the paint had to be removed. So much to proprietary right at buildings.
And there are some public buidings where the arcitect did not comply to regulation and then the buildings were closed down.
