I specifically hunted down a Cu24 in Emerald Green. Why? I had seen Steven Wilson of Porcupine Tree play an Emerald Green PRS, probably a Cu22 (he seems to prefer those), back in the early/mid-2000s. When I finally got the gumption/wherewithal to buy a PRS, I decided not to compromise, including finally getting a 24-fret guitar (sorry Mr Wilson!). I already had a nice maple-flame-top blue guitar (Godin Freeway classic), and a LP with a classic cherry sunburst, and a tele in natural ash, etc. Green had appealed to me for years for some reason, and they are indeed not a common color to stumble upon.
So the Emerald Green was on the must-have list. Curiously, my co-worker has an Emerald green Cu24 10-top (Artist Package) - he's had it since new in 1999-ish. He didn't curb my enthusiasm at all, oddly enough.
Now that I have it, I do not intend to ever let it go. It is quite nice looking, and although not the best "10 top" I've ever seen, still nice enough for me!
