Abstract

Methods of coating contacts to have a specific color. The color can be selected to match a color of a portion of a device enclosure for an electronic device housing the contacts. Examples can instead provide methods of coating contacts to have a color to contrast with a color of a portion of the device enclosure. These methods can provide electrical contacts having a low contact resistance and good corrosion and scratch resistance.
