Change the Eye's Color

In this tutorial we will learn how to use 'Hue / Saturation' Adjustment Layer to change the Eye's color.

First, open the picture, the eye (you can get it from Google). double click the background layer and rename it. Then add the adjustment layer by clicking the icon on the bottom of Layer's pallet. When the window show up, set the value of Hue and saturation to +99 and +25, we are looking for the light green, click OK when you're done.

Now we're having a totally green picture, but we just want to change the middle part of the Eye ball.

Second, lets take a look at the top most layer, look at white box, we'll fill it with black color. Click the white box and hit Shift + F5 or you can try Edit > Fill and choose Black.

Last. we will show the green color back but only in a pupil, the middle part. Click the mask (the white box we just filled with black), use the brush tool ( shortcut : B ), set the foreground color to white and you can start to paint that part.

Note : when you're done, and you still wanna change the eye's color, simply double click the thumbnail of Hue / Saturation layer and set the both value of hue and saturation.
