I have several different Titaniums and have three different colors
From left to right: Gunmetal, Titanium CE, Titanium, Titanium SE, Silver, Handmade.
I have two CEs. One came with the darker gray and one came with the lighter. The two SEs I had both had unplated cores and looked like the same color as Silver. The Handmade seems like the same color but you can see slight machining on the sleeve. The CEs have serial numbers like CE xxx TI. The SEs have serial numbers like TI (SE) xx-50. I also have a Titanium with the darker sleeve with a TI000xx serial number.
