I've been searching around for a tutorial on getting incredibly clear colouring from screencaps. Possibly the most famous for this effect is

I see different users have managed the same effect, but there isn't a tutorial anywhere (or I am missing it every single time I look).
So can anyone point me in the right direction? Perhaps these people have an expensive magic wand they wave in front of their computer screens?
By the way, I use Photoshop CS. Thanks anyone for their help.
