Sputterng is more often used technology as you thought. Usualy this technology is used in your cars where you have “chromed” plastic parts in interior. Most of the parabolic in the front and rear lights is also made by this technology. Sputtering or “chrome look” is made by evaporated aluminium in vacuum which cover the plastic and then is covered by transparent lacquer.
The chrome effect doesn’t have to be always “silver” the color of the chrome surface can be adjusted by adding color ink to the transparent lacquer. Then you can have colored chrome effect as you wish.
The surface aslo doeshn’t have to be shiny with high gloss effect. Everything is affected by the preparation of the surface so for example grainy look is possible.

– part size
