Eye re-enhance - Step 2!

What I usually do is I take the lightest color from the original eye and on a new layer and color the lower part of the eye that color keeping the pupil visible. Then I go around the edges of the eye with a darker color for the "rim" of the eye. Then I add little dots of a lighter color, but darker than the original color used around the lower part of the eye. As you can see it's kind of blocky at this point then I add black to the top of the eye where the pupil is and add a very light color where the original highlight is.

Step 3!

For this I add another layer and color block the eye with a dark color, I usually use the same one that I used for the rim of the eye. and then I erase with a soft brush in the middle where I would like the focus to be.

Step 4!

Almost done! In this step I just add itty bitty details, like flecks of new colors, added highlights lowlights, and I generally just give the eye a finishing touch! I generally redraw the white of the eye in this step making it a bit more defined, as well as the eyelashes and outlining the eye. Now you're done!

Color changing/Patterns

Step 1, take that finished re-enhanced eye from before and select the actual eye color, the iris. Copy and paste it onto a new layer and mess around with hue and saturation as well as the tone. This is a really fun thing to mess with since you could get things like this!
