Vibrant Eyes for Genesis 2 Female and Genesis 2 Male gives you a wide range of Iris colors for all your character needs, whether they're humans, elves, faeries, monsters, werewolves or vampires. You can use this set with any character, as it only replaces the iris and pupil textures and use the default UV for each.

There are 96 color options in total, plus five additional mats that apply only to the ambient channel as masks, so you can change the look of the existing colors presets. You can also use any of the color maps in place of the ambient masks and create an even more unique look.
