As others have said, anodizing a handle scale or pivot screw, standoff etc. can be striking when done nicely. There is flame anodizing and electric anodizing. Electric gives all those stunning shades of blue, green, yellow and purple to name a few. I have a Hinderer spanto fatty that has a blue anodized lockside. All working finish. The scale (g10 side) is blue with black bits. The ano blue and the g10s blue are the same shade. I think it looks nice and adds character to the knife. The color of the ano and what it complements on the knife are important.
I know the 228 w/ the blue ano you're talking about. I think it looks great but that's just my take. Another guy might hate it. I happen to think it works really well. For me though--if I were making the decision you are about to--I would forego the factory ano 228 and buy the "plain" one. It's just b/c I don't favor the holes in the handle. I would get the solid handle grey one and anodize it after-market. If you like the color of the blue clip Chaves sells for the 228, you could have your handle anodized to match it. That would be a nice look.
Remember also that titanium can be re-anodized too if the color wears or gets scuffed and things like that.
