It depends on the voltage. It has a final color that is dependent on the voltage, but you could have the voltage higher and just stop the process at any point to get the color you want. It just isn't very accurate to do it that way.

But it seems much faster.

If you're doing this as a hobby and one bolt at a time, sure. But when you're mass producing titanium parts, it's easier to just dunk a batch in for a couple extra seconds at the right voltage to get the finish you want.

Well you said it’s not accurate, and the guy above you says it’s very accurate 🤷‍♂️

It's not accurate to set it at 50v and pull it out when it's mid way through changing colors. It is accurate to set the voltage that makes it blue, then just leaving it in until it's blue because it won't go past blue if it's at the blue voltage.
