I really don't think people have "caught" that you can use that template to not only make your own Metal custom color sets as it has the lines and shadings I used for the color accents, but that you can also switch off those layers and in the matter of a few clicks create yourself say a set of red titlepanels to replace your standard blue ones if you'd like
Glad you found it helpful

There really are tons of those tutorial sites too; a lot of them are basically indexes that pull together sites that have say 10 different tutorials available so once you start with one you can bounce around checking things out picking up tips almost endlessly. The techique I used to create the "look" of my Etched Steel Skin (link to the
screenshot) came from a tutorial on creating textures for example.
