Heraldic Coloring (PHOTOS)

In the regional centre the emblems of Uzhgorod and Transcarpathia at the front of Uzhgorod Commercial College were recently painted in a "creative" way. Apparently, the artists have not learned about the features and color gamut of the regional heraldry. Uzhgorod.in offers readers to find the differences. 

Meanwhile, the question arises: is that lawful to treat the official symbols of the region in one's own way and how much "artistic imagination" may be added to the image of the emblem of the regional center and the region in general?
