Well, that exact swirl is probably not going to be possible in ink, dye, or paint, but a rainbow anodize should be possible with a little creative engineering. IIRC, the color of the anodize isn’t directly related to the anodizing itself. It is a separate dye added in a (somewhat) separate part of the process. (again… IIRC) So, a motivated person could use several different colors of dye applied with ink-jet in rapid succession, during the normal colorizing part of the anodizing process, to get a rainbow of colors in the finish. It would mean installing an ink-jet machine in place of the color process machine they use for ‘regular’ single-color dyes. And, a bit of R & D to figure out the best work flow to get decent results.
The new colors are cool, but I can’t really say I’m excited about it. I already have 18650 tube lights in red, green, blue, silver, bare, grey, black, brass, and titanium. And some slightly shapelier ones in copper. And more colors in other battery types. So it’s still cool, but I’m kind of swimming in lights already.
Like the purple. I think a LOT of manufacturers overlook how popular optional colors are. Many lights that come in black only could boost sales with colors like Convoy offers.
The new colors look great. I still prefer my flashlights in (boring) black. So that would make the S2+ available in black, grey, silver (clear), blue, red, green, tan, orange, purple, and cyan. Wow!
I agree with Persechini above, I wish they were available with a rubber boot. I’ve always wanted to match lighted tailcaps to the various S2+ colors. A lighted tailcap with a metal switch does not work as well.
I think they all look good, but my favourite is the cyan. However, I think slightly deeper shade would look even better. The cyan D4 is my all-time favourite flashlight colour.
I’d like the orange, but am with those who think it could “pop” more.
As an aside, has the silver/clear proven to be any more or less durable than the other colors? I seem to recall that while those hosts do have a coating, it wasn’t expected to be on the same level of toughness as the others.
