Flatpicking Guitar magazine reviewed these neon colored strings from DR this month.

Seems like a really cool idea for teaching purposes. No more saying, “Pick the G string” or “Pick the third string from the bottom”. “Pick the orange string” seems much easier, especially for kids. It’s such a simple idea, I’m surprised someone hadn’t already thought of it.
I’m tempted to try a set just to see what kind of comments I might get at my jam.
I suppose you could consider them “coated strings”. 
Looks like they might be easy to see in the dark too!
They look interesting and would be good for teaching purposes, thanks for the post.

I want to get a set and take my guitar to the bowling alley when they have all the black lights going.
They would probably look great on your Hello Kitty.
Yessir!
They shoulda made them the same colors as the strings on that guitar hero game: green, red, yellow, blue, orange…
Looks to me like a gimmick to dumb down (retard) learning.
It is harder to re-learn something that is first learned wrong than to learn it right the first time.
So, if doing a double-stop of red and blue strings it is a purple note? Learning how to communicate with others, and understanding the relationships of notes is integral in playing in my opinion.
Though I’ll admit to playing a blue note from time to time, and one of my all time heroes; Roy husky Jr. thought of musical moods as colors, I think I’m totally against this type of short-cut, short sighted, gimmick teaching.
Interesting viewpoint, fiddlewood. I didn’t really consider the strings a gimmick but more a learning tool, not too dissimilar from Ben’s McPherson having the fret numbers inlaid in the fret board. I guess if reliance on string color became too great it could be a hindrance, though. A person might get some weird looks if they asked someone to play the purple sound. 
I spoke with a guy at Guitar center and he said he would not recommend the strings as they are a novelty item and the coating comes off to soon so I avoided it for that reason . when I have some money to waste (that would be rare) I might try a set . Loving the Martin long life strings though they are top notch. I could not believe how the bass sounds wow ! light gauge at that .
