Today I'll show you how I change the eye color of my model(s). This is just my way of doing things, there are a lot of other useful tutorials out there, you are more than welcome to try out those instead.
I am using ibispaintx for the purpose of this tutorial, but any editing app where you can work with layers will do, and an image of a random model that I found on pixabay, because he has a prominent eye color.

Once you are done with preparing your base and putting your face claim, add a new layer above the layer of your model and change the blending mode to color.
Pro tip: Always do all your editing on separate layers, that way it will be easier if you have to delete something specific or undo a little mistake.

We are going to draw over the actual eye color of the model, I'm using airbrush (normal) for this.

Select a color of your choice. I chose a blue green hue.
