Long Curve - Shocking Pink + Long Line - Nebula

Anodized Titanium gets its color from an oxide layer that forms during the anodization process.  This layer is on the surface of the metal and, as such, should be protected from scratches.  Storing your earrings in their original box or somewhere isolated from other jewelry is a great idea.  Surface contaminants like oils from your fingers may also dull the color, but a quick buff with a clean cotton cloth will restore them.
