So, the Pantone color of the year for 2017 is "Greenery":
NY Times article does the best job I've seen of telling how Pantone arrives at these decisions.
I've had a partial entry for this up and ready to go for a couple of weeks, because I knew they always announced this in early December, but then when they finally announced it I was busy and it took me a day or two to get back to it. I had done a little speculating about what it might be. I had seen a blogger predicting Hunter Green for 2017, and another one saying Kale, I believe, but I wasn't sure Pantone would pick any green because Emerald was the color of the year only a few years ago. I've seen various theories about how Pantone chooses - bouncing around the color wheel, for example. My semi-educated guess was yellow, because they haven't had a yellow since 2009. I knew there was a yellow (Primrose Yellow, I believe) on their spring 2017 list. But Greenery was also on the spring list. And for that matter, Greenery is a yellow-leaning green, so I wasn't actually all that far off, there, still.
I'll have to come back later to the issue of what polishes might be close to this. (The one that pops in my head from my own stash is Ivy League, but really it's more lime than I think Pantone really had in mind.) (Kaboom is also shown with Ivy League, and I noticed somewhere a quote about Pantone saying that Greenery was "warm plus cool" which is pretty much literally what Kaboom/Floam is - a chartreuse green plus a blue-green. So to some degree that might be pretty close to the mark, too.)
Pantone put up a cool little clip on their Instagram showing the color being mixed. (I'm always saying I need to spend more time on Instagram. I was all into it early on - by which I mean years ago, now - and then now that everybody else has jumped on the bandwagon, I find it a little overwhelming! But there's a lot of good information that I miss because I don't mess with it enough.)
(Added: I've poked around some and honestly, I'm not finding a whole lot of nail polishes in colors like this. I hope every polish company has some in their spring collection - those should be coming out right away, anyway!)
Here's some more articles from different sources. I always find that reading different articles about the Color of the Year gives me a better overall picture of what Pantone was going for. Pantone's own announcements are sometimes sort of... opaque.
