You missunderstood, sorry if i where unclear.

What i am pointing out is that materials and in particual metal and reflectie materials have a hard time to look like the real thing when done from specified values. Your Steel text and its colours will work exelent on lets say a homepage where the colourset is very dark unsaturated blueish and souch, but would just look completly wrong in a homepage with a light-orange/red/pink colourset. Its like the saying "Give a man a fish and he will be fed for a day, teach a man to fish and he will be fed for his life." It would be better to teach people the theory behind the effect so that they may customice and use it as they will rather then to give them a static settings that create a effect that only works sometimes.
Also MR_LAGI, That Signature you have there, could you tell me where is the light comming from? You have a srong one going across your background from the right. But all the speculars of the holes and other components use the light from a source coming from the top of the image, a blue orb that sends out white light not affecting the pitch black area just above, and the wires arent affected by any light at all.
To be honest, Photoshop is crap att handeling reflections and glossyness and faking metals require both a good eye and serious thinking. To be left for 3d apps for the best results as its a mathematical operation. Seeing the metal applyin its enviroment as its texture is what real make you beleve its metal.

Thease are some PS made examles i made trying to prove my point. Not perfect but PS alone will never give you beleavable mettals unless you hand draw them and take unessesary quantetys of time to study and go back over and over again.
Colouring, speculars, reflection and shadows. All are enviroment dependant and should be custom made for each purpose, IMO anyway.
