Actually, there is a method to the madness of the pretty colors.
Titanium is VERY prone to galling. Hence, their discontinuance of the titanium turret bolt in favor of Monel. It makes for easier, vs near impossible disassembly after overtorquing.
Well, after acid-anodizing, galling is significantly reduced: Titanium and Titanium Alloys - Acid and Alkaline Anodising of Titanium Alloys
It also improves wear resistance. Titanium, although strong, still scratches easily. And acid anodizing also adds pretty colors.

You see, there actually is a downside to titanium beyond its flammability. When two parts gall together, it's a crazymaker separating them.
Here's a neat (scary) thing to try:
Take your fancy T2x and tighten down a port plug extra snug. Don't worry, it's titanium, you'll still be able to unscrew it. Now take it into an absolutely dark room at night. Unscrew the port plug. See the tiny spark when you do. Think about that with pure O2. And that's why they don't use titanium in deco regs.

Titanium color anodizing makes titanium parts easy to identify by color, and is used on implantable medical devices such as bone screws.

@Wiznutaggie :
Is this the T25 or your own handy-work on a T1/T2 first stage? Looks very nice. Is the anodization solely on the exterior surface of the first stage or on the interior surface as well?

Looks good.

I decided to overhaul.my 20+ year-old B2 the other day (that was still working fine and had never been overhauled). A tad more o-rings than I expected but otherwise everything went back together and it breathes as effortlessly as when it was new.

Thanks, it's my own handy work on a T2. Everything is anodized, including interior.

Sweet, I didn't even know about the decreased galling. That'll be a nice benefit. On disassembly the din nipple was seized like hell onto the body. Took a good bit to break it free.
@Scuba Lawyer Did you reuse the old seat or install a new one? It would be great to know a seat can last 20 years.
