So it's not impossible to get these colors witha similar or greater hardness. But it wouldn't be titanium-nitrite.
The reason I suggested an oxide is because it's generally harder and more corrosion resistant. As opposed to PVD coatings which break at high-speed impacts.
Can Adamantium exist in real life? And Cap's shield and vibranium?
