Temperature titanium turns blue

Does anyone know what temperature titanium turns blue?

Just a question of curiosity as my exhaust tip is turning slightly reddish with a hint of blue.

Titanium melts at approximately 3200F, so it probably turns color somewhere between 2500F and melting point...I think. Just a rough guess.

I really don't think your exhaust temps could make it change color. Some exhausts (such as Megan) already have a colored tip.

You're not melting it, your oxidizing it.

Ti will start turning oxidizing/nitriding from ~400C up. Higher temp will accelerate the process.
