Help with digital selection [ANSWER]

On the "VLab" page, it says VLab can do digital selection (in the example, the man's face turned blue, and his eyes shined). I double checked, and there is no video tutorial on how to do digital selection. Anyone knows how?
(I want to do pretty much the same effect: changing someone's skin colour.)

The method is to duplicate the layer and use garbage mattes or masks to define an area to be graded. Have a read through this tutorial

Alternatively, to avoid unnecessary duplication, you can usually simply place a Grade Object above the clip in question, then apply a mask to the grade object so that it only affects the parts desired.
For the blue soldier effect that's exactly what I did - loose masks with a fair amount of feather around his face and ears and hand, then graded those sections to blue. I also performed a basic chromakey on the vegetation in the background as a quicker way of isolating the soldier from the background (thus avoiding turning the background blue, but without having to painstakingly mask around the outside of his head).
The shot was from Between the Lines by Ashley Wing, in which the soldiers aren't blue. If I was to make a film with specifically blue soldiers (or similar), I'd take steps to make the process even easier - using on-set make-up would likely be quicker and easier than doing the entire movie in grading.
I'd take a look at some Sin City behind-the-scenes and how they accomplished the Yellow Bastard. They basically painted the actor green (I think), which enabled them to key him out from the surrounding footage, isolate him and turn him to whatever colour they wanted, while grading everything else separately.

Just a little note: Sin City used greenscreens for the most part, so Yellow Bastard was actually painted blue. They tried the yellow makeup, but yellow is such a close color to green that there was too much bleeding into the background.

Thanks!! But how do you do a glowing eye, like the blue soldier's?

Essentially the same way. Select the eye, change the color. In that specific example, Gleam was used to add to the glowing effect.

People have told me when I make this one face I look like Yellow Bastard. This upsets me, because although I have never seen Sin City, I'm pretty sure this isn't a compliment.
