The Dark Brown Interface for Content Patcher is an addon that will change the color of the in-game items, furniture, and even the background. It works by modifying a game file that is loaded when you first start the game, so you won't need to download anything extra to use it.

This addon is meant to be used in conjunction with the Dark Brown Interface for in-game items, which you can find in the app. The two addons will work together to give you a dark, brown interface that you can use to change the color of all the items in-game.

To activate this addon, you need to open the game file that contains it, then go to the section that you want to modify, and make the changes you want.
