S2+ Question ... 18650 and 18350

I suspect this topic has been covered on the boards before but I couldn't locate a discussion.

Have an S2+ (18650 tube) on the way and was going to get an 18350 tube as well ... But I've seen several reviews stating that people ordering 18350 tubes in gray are finding that the gray shade doesn't really match. Anyone know anything about this. Thanks!

Yes ,the tube from Banggood is different gray shade , at least mine.
I turned my short S2+ in white aluminum.


Thanks!
