Titanium Anodizing
Color Chart
Complete reference guide for titanium anodizing colors. Unlike aluminum anodizing which uses dyes, titanium produces colors through an oxide layer interference effect. The color is determined by voltage, not pigments.
Titanium Anodizing Color-Voltage Reference
Colors achieved through Type II (standard) titanium anodizing process
| Color | Voltage Range | Oxide Thickness | Notes |
|---|---|---|---|
Gold / Bronze | 10-18V | ~25 nm | First color achieved. Warm, elegant appearance. |
Purple / Violet | 18-25V | ~35 nm | Popular for jewelry and decorative parts. |
Blue (Dark) | 25-35V | ~45 nm | Deep, rich blue. Common for automotive and aerospace. |
Light Blue / Cyan | 35-45V | ~55 nm | Bright, vibrant appearance. |
Green | 45-55V | ~70 nm | Can range from teal to forest green. |
Yellow / Gold | 55-65V | ~85 nm | Bright yellow-gold. Second cycle of colors. |
Orange | 65-75V | ~95 nm | Warm orange tones. |
Pink / Magenta | 75-85V | ~105 nm | Vibrant pink. Popular for consumer products. |
Purple (2nd cycle) | 85-100V | ~120 nm | Colors begin to repeat at higher voltages. |
Grey / Muted | 100V+ | ~130+ nm | Colors become less vivid at very high voltages. |
How Titanium Anodizing Works
Unlike aluminum anodizing which uses dyes to add color, titanium anodizing creates color through thin-film interference. The anodizing process grows a transparent oxide layer on the titanium surface.
When light hits this oxide layer, some reflects off the top surface while some passes through and reflects off the titanium beneath. The two reflected beams interfere with each other, creating the visible color.
The voltage determines the oxide thickness, which determines which wavelength of light is enhanced through interference - thus determining the final color.

Titanium Anodizing FAQ
Is anodized titanium color permanent?
Yes, the color is very durable because it's part of the oxide layer, not a surface coating or dye. However, the oxide layer can be scratched or worn through with abrasion, revealing the base metal. Re-anodizing can restore the color.
Can you get exact color matching with titanium anodizing?
Color matching is more challenging than with dyed aluminum anodizing. Factors like alloy composition, surface finish, and process conditions can affect the final color. We recommend sample parts for critical color matching applications.
Does titanium anodizing add thickness?
The oxide layer is extremely thin (25-150nm), which is negligible for most applications. Unlike aluminum hard anodizing, titanium anodizing does not significantly affect part dimensions.
