This tutorial will focus directly on changing the colour of the eye and the eyelid.  This is generally a beginner how-to, but this technique can be applied to more advanced colour manipulation that you require for your digital media.

Step 1

The image below is a random eye image found doing search, I recommend you try using one your own photos. Open the eye image in Photoshop CS/CS2 or version 7. The technique can be used on all version of Photoshop.

Step 2

Create a new layer by clicking Layer -> New -> Layer
Give the layer a name, preferably something meaningful e.g. Eye Color. This is the workspace that we will be working in to change the color of the eye.

Step 3

Select the Magnetic Lasso Tool. Now with a bit of care trace around the eye edges until the desired effect.
