Although there is a “space gray” option for the MacBook series, there has never been a “real” black. Recently, an Apple patent was exposed, mentioning the steps and related features of coloring metal parts.
According to the patent document, the general anodizing technology can only leave limited pigments on the metal surface, so most commercial “black” products are not really black, but dark gray or blue. The solution mentioned in the Apple patent is to add fine holes on the surface to enhance light absorption, making the surface look darker while continuing to maintain the matte effect. The patent also indicates that this technology can be applied to different metal surfaces, including aluminum, titanium and steel.
In fact, Apple itself has tried to launch products with a black metal surface, such as the iPhone 7, but it is not very resident in color matching. In the past, there were complaints about easy scratching and the like. Therefore, whether this new design can solve this problem is still exciting. .
