Change Hair And Eye Color is an app that lets you do exactly what it says on the cover. You can select any picture on your device and edit it to make it look like the person's hair and eyes are a different color.
From the app's main menu, you can choose if you want to change the color of your eyes or your hair. Each one has its own process and follows certain steps on a custom interface. To change your eyes, you have to adjust the outline of your eyes and then choose from more than 500 different lenses.
The hair color feature is what takes a bit more time, since you have to manually trace the outline of the hair. That done, just choose the hair color you like best, along with the opacity and saturation of the color. And when you're done with that, you can add even more effects if you want.
Change Hair And Eye Color is a good photo-editing app that lets you see how you'd look if you dyed your hair or got colored contact lenses. Not to mention it's quite fun to mess around with.
