Blue Colored Titanium Rings. We also make colored titanium rings in black, green, red, purple, and white. The Blue Colored Titanium Ring comes from a titanium anodizing process that actually puts the color into the surface of the aircraft grade Blue Colored Titanium Rings. Blue Colored Titanium Rings have a unique sheen that illuminates and reflects off the titanium. Also, take a look at our Engagement, Mens, Colored, Celtic, Titanium, Black Bands.
