If all you need is a change of color, consider constructing a dyer's table to dye your armor. The nice thing about dye in Conan Exiles is that you can choose different portions of each piece of armor to either dye different colors or leave their natural color. This means there are thousands of combinations for each piece of armor and no two players will look alike. If you want to change how your armor looks completely, consider investing in sorcery and casting an illusion on your armor. In this way, you can make any armor look like any other piece of armor that your already know how to craft.
