What distinctive color identifies titanium in microsurgical instruments?

• A. Green
• B. Red
• C. Blue
• D. Black

Answer: (C)

Titanium is identified by a distinctive blue color in microsurgical instruments. This blue hue is achieved through an anodization process, which forms a thin oxide layer on the surface of titanium. This layer not only generates the characteristic color but also enhances the material's corrosion resistance and biocompatibility, making titanium particularly suitable for surgical applications where strength and lightweight properties are essential. The blue color serves as a visual cue for healthcare professionals, allowing them to easily distinguish titanium instruments from those made of other materials, which can improve efficiency and safety in the surgical setting.

The other colors listed do not correspond to titanium; each may relate to different materials or coatings, but blue is specifically recognized for indicating titanium in the context of microsurgical instruments.
