Purple Titanium
how do they make the titanium shift knobs turn purple ?
lets just say I had a bad day with my shift knob, and I sandblasted it. I'll blame it on being drunk for now.

That is the color it turns when heated by open flame....So just like the other suggestions take a torch and "burn" your knob .... giving it the purple color..... might as well mess around with it sounds like you already messed it up my sand blasting it....what else do you have to loose.
If you do take the torch to it.....post some before and after pictures.

It's not burning it. APplying heat will change the color but it's very sporadic.
The right way to make Titanium purple is by anodizing it, that is, applying an electrical current to the metal. I think purple is done with 100 volts or so, maybe a bit higher.
If you want to turn this into a science project, find a variable voltage DC generator (something that can go at least 120 volts) that is capable of like 10 amps, some diluted phosporic acid (a cola soft drink would work though I'm not sure how "clean" the end result it), a scrap strip of titanium, and a glass jar big enough to submerge both pieces of titanium (but without touching). Hook the power lead to your knob, the negative/ground lead to the scrap, and dunk them both in. Not sure how long it takes, but I don't think it's more than a few minutes.
