Color Customization and background customization
Name says it all. Should be able to customize the color of your buildings so that it is your own unique village. The color of Town Hall 10 gives an evil atmosphere of the base but what if I don't want to look evil. I want to look good. Some buildings could be exceptions such as inferno towers because they emit fire. But other buildings such as archer towers, mortars, and cannons can easily be customizable in terms of color and still have the same power.
You can also add a gold price if you want. If I want to change it, it would cost 100,000 gold per building or something like that.
Also, clan castle colors should be the same for all members of a clan. If you are not part of a clan, it would go to the default colors.
