I suggest painting the whole buildings of Yerevan.
There are many buildings like this in different cities of the world and this kind of buildings will give a unique look to the city. Such buildings are called "Rainbow Buildings".
With the principle of balanced development of Yerevan city, Mayor Taron Margaryan instructed to have the external look of the high-rise buildings refreshed.
The appearance of the buildings is being modernized by the program of frontal parts coloring which is carried out in different districts.The number 14, 15, 16, 17, 18, 19, 20, 21 buildings of 16th block of Ajapnyak district, the Acharyan 44 building of Avan district got a decorative look as well as Babajanyan 165 and 167 and Isakov 46 buildings of Malatia-Sebastia district got a unique colorful decoration.

Thank you for interesting suggestion.
