The color of target rings and the arrows that appear below targets can be changed from Display Name Settings in Character Configuration. Under each tab, a colored dot next to the various types of target indicated the color used for the target ring.

* Changing these settings also affects the color used for the display name and associated icons.

First, access the NPCs tab of Display Name Settings. There are four options that affect enemies, and you can select a color for each one separately. Selecting a colored dot will allow you to change the color. Once you have finished making your selections, press Apply to save your changes.
