Anodise is voltage, not pigment.
A short explainer on the 24 V titanium band, and why the colour is the oxide layer.
Anodising isn't dyeing. The colour comes from how thick the oxide layer is, not what you added to it. Titanium sat in an acid bath and run at a controlled voltage grows an oxide layer measured in nanometres; light bounces off the top and bottom of that layer and interferes.
12 V gives you bronze. 24 V violet. 36 V blue. The Ti-Ox Headset is run at 24 V, so the whole run ends up the same shade: the bath, temperature and current density don't vary.
The colour can't chip, because there's no pigment. It can wear (the oxide is thin), but it'll wear evenly. And it never matches a Pantone number, because the colour is light, not paint.
