blahblahblah said:Well if you REALLY want to get fancy, consider a TiCN or TiAlN coating. The lights would have a finish which is like a Blue/Gray or Violet/Gray color. :rock: That would be a flashlight/torch first !!!
Here's a link to several coating types/colors to give you an idea.

BTW, I use TiAlN drill bits to drill stainless steel. They hold an edge better by reducing the friction and subsequent heat.
Your machinist may even use TiAlN coated tooling for the Ti machine work.
These guys do tool coatings internationally http://www.balzers.com/
Also, check out this picture of a SOG Rainbon Titanium Nitride coating:
