Yeah you can download torrents from internet. It's just that usually illegal stuff is downloaded using torrents and our goal here is not to promote this idea therefore such topics aren't discussed in public here.
Take picture of the screen and analyse for the colors once you found the color you want then stop and lock mouse.
The color around the players is usually done through CHAMS(search my videos for it for more info or just google it)
I mean a screen shot of your games display, for example taking all the colours of the screen pixels into an array and then analyzing it.
If your still having trouble with the logic I recommend you try and do some slightly easier hacks and then move on to other stuff such as this.
