Trends in Byzantine Empire architecture

I feel by looking at a lot of the images that most of the buildings they had were made of brick and had the same color and shape of buildings throughout. All the images had something to do with religion too. The pictures had many different colors that would stand out and you could notice them. A lot of pictures had weird designs that were had to tell what they truely were. Like i said the pictures had many different colors in them and made somethings stand out more then others. It showed more important things or pctures in a more distinctive color then other things in the pictures. I feel that is is both to be functional and decrative because they want all their buildings to serve their purpose and things like churchs to be built the way they should be built but at the same time i feel that they try hard to keep all their builds and painting decrative too so they can stnad out and be noticed by everyone. I feel like their was a little bit of influence on American on the way they built their churchs and also they way they drew God. I felt like looking at the pictures of their churchs they seemed very similar to some of the old churchs that are still around today in America.
