Electronic device housing and method for making the same

An electronic device housing, comprising:

• a substrate;
• a plurality of first metallic coatings formed on the substrate by vacuum sputtering or vacuum vapor deposition, the first metallic coatings comprising a plurality of niobium pentoxide layers interleaved with a plurality of silicon dioxide layers;
• and
• a plurality of second metallic coatings formed on a portion surface of the first metallic coatings by vacuum sputtering or vacuum vapor deposition, the second metallic coatings comprising a plurality of niobium pentoxide layers interleaved with a plurality of silicon dioxide layers;
• wherein the regions of the second metallic coatings present changing and shifting color patterns or letters when viewed during a movement of the electronic device housing relative to a viewer.
