Adding Expanded Grayscale Bar

[Ghoul]

I've been making a special build, and I want it to be as authentic as possible. To do so, I need a more detailed grayscale bar. I've seen this on several severs; the default paint set, with an extra bar containing an expanded grayscale. I'm a complete idiot when it comes to editing scripts of any kind, so I'd like someone to tell me how to add this modification.

I don't want any "use search" crap. I tried.

Its not a script.
base/config/server/colorset.txt

Just look for a Color set that has a grey scale you like. Now, look for the Greyscale numbers then copy them all [including the DIV I belive it's called] Then paste it somewere in your current Colorset.txt
