KEPLA-COAT plasma chemical coatings are usually white to gray-white in color. The color ultimately depends on the alloy and coating thickness. The result on high-strength alloys is usually a grayish white, whereas common alloys adopt a white color. The higher the coating thickness, the grayer the coating appears. Copper-based alloys have a slight pink tint to them. However, it is also possible to create black coatings.
