Question on customizing tabs in a DPropertySheet

I have been messing around with gui more and more as its an aspect of garrysmod I love to play around with. With that being said I cant seem to figure out one main thing that has been bugging me for some time.

How do you directly edit DPropertySheet’s tabs? Just to be clear I am talking about these on a property sheet -->

I have seen people with really fancy huds and guis all of which change the look of the property sheet’s tabs and I would like to know for myself how to do this. Thanks for any and all help in advanced!

But don’t skins override all derma elements you skin instead of just the ‘project’ being worked on or am I mistaken?

The skin is applied to all panels you use SetSkin on. It won’t touch other panels.

Or you can paint them manually:
[lua]
for k, v in pairs(PropertySheet.Items) do
if (!v.Tab) then continue end

v.Tab.Paint = function(self,w,h)
	draw.RoundedBox(0, 0, 0, w, h, Color(math.random(0,255),0,0))
end

end
[/lua]
