Aurora is an addon that restyles the default Blizzard interface to a clean, minimalistic theme that is consistent across the entire UI.
A lot of time has been spent on not only basic development and updates, but also refining and perfecting the appearance of each window and every frame.
A single color that matches your current class or is a color of your choosing is used for highlights and emphasis.
Open the Aurora options from the in-game addon options, or type /aurora.
