Anodized titanium creates vivid interference colors without dyes—the color comes from the oxide layer thickness grown by voltage. Below is an approximate 10–100 V range covering the full spectrum we can produce in-house. Note that red is not achievable via titanium anodizing due to physics of thin-film interference.

Custom work: Any of our titanium fasteners can be custom anodized. For deeper background, see our anodized titanium article.

Anodized titanium color spectrum from 10 to 100 volts with sample swatches
Colors are produced by voltage-controlled oxide thickness. Lighting, alloy, finish, and viewing angle will affect perceived color.

Approximate Voltage → Color Guide

Based on our in-house anodizing chart (10–100 V in 2.5 V increments). Exact hues may vary with alloy, prep, and lighting.

Voltage (DC) Typical Hue Notes
10–15 V Bronze → Brown Earliest anodized shades, warm metallic tones.
17.5–27.5 V Dark Purple → Light Blue Smooth gradient from purple into lighter blues.
30–47.5 V Faint Blue → Silver Transitional, more muted on matte finishes.
50–60 V Yellow/Gold → Rose Gold Bright metallic yellows warming into rose tones.
62.5 V Pink Delicate, pastel pink hue (angle-sensitive).
65–75 V Purple Tones Richer purples reappear at higher voltage.
77.5–85 V Blue & Teal Bright ocean-like colors, very vivid.
87.5–100 V Green → Yellow-Green Upper range; greens transition into lime tones.

Reminder: Red is not achievable in titanium anodizing. The physics of thin-film interference simply won’t allow it.

Reminder: Red is not attainable with titanium anodizing.

Finish, Prep & Consistency

  • Surface prep: Polished parts look more saturated; blasted/matte parts appear softer/pastel.
  • Alloy: Commercially pure (Grade 2) and Ti-6Al-4V (Grade 5) can differ slightly in hue at the same voltage.
  • Geometry: Heads, recesses, and threads can reflect light differently; expect minor variation part-to-part.
  • Post-processing: Oils/handling can mute color—clean gently with isopropyl alcohol and a lint-free cloth.

Ordering Custom Anodized Titanium

  1. Choose your parts from our titanium catalog.
  2. Select your color (or voltage target) on the anodizing page.
  3. We prep, clean, and anodize to the requested hue. Most small runs complete quickly; large or mixed batches may require extra time.

FAQ

Can you do red?

No. True red isn’t possible via titanium anodizing—the optical film never produces that wavelength as a dominant reflection.

Will the color wear off?

The oxide is integral to the titanium surface (not paint). Abrasion and harsh chemicals can still dull or shift the appearance over time.

Can you color-match exactly?

We can target a voltage/hue, but small batch-to-batch variations are normal due to alloy, finish, and geometry.

Do you offer multi-color effects?

Yes—masking and multi-step anodizing are available for select geometries. Contact us with details.
