彩虹葡萄 新品種還是PS產物？

With digital software like Photoshop being used ever so often to alter things so perfectly, it’s hard to tell what’s real anymore. Take these photos of the so-called ‘rainbow grapes’ that have been doing the rounds online for about a month. They’re about the coolest-looking fruit I’ve ever seen, but are they real?
隨着PS軟件的流行，人們P出來的圖片也越來越完美，有時候真的很難分辨我們看到的圖片中哪些是真哪些是假。就以近一個月來在網上流傳的彩虹葡萄爲例，這些葡萄的顏色可以說是我所見到過的色彩最豐富的水果了，可是它們是真的嗎？

Well, yes and no. Rainbow grapes do exist, but they are just regular grapes photographed in a ripening stage known as Veraison, or the ‘onset of ripening’. “When grapes go into the final stage of ripening, the young immature grapes have a very dark, opaque green color and a very hard texture, like little rocks,” said Larry Stone, master sommelier and restaurateur. “And then when they go through veraison, the skin goes through coloration. If they’re white grapes, they go from a dark green to a kind of yellowish green color, and they get more and more transparent. A red grape will go from a green color to a red color. The shade of red depends on the variety of grape.”
實際上，彩虹葡萄是真實存在的，只不過它們是普通葡萄在轉色期時的樣子罷了。轉色期就是葡萄漿果快要熟了，開始變色了。侍酒師和餐館管理者拉里說：“當葡萄進入成熟期的最後一個階段時，尚未成熟的葡萄會呈現出不透明的深綠色，此時它的肉質很老，就像小石頭一樣。當葡萄處於轉色期的時候，它們的表皮會經歷各種顏色的變化。如果它們是白葡萄，它們就會從深綠色變成某種淡黃綠色，並且會變得越來越透明。而紅色的葡萄則會從綠色變成紅色。其紅色的深淺取決於葡萄的種類。”

And at the end, once they’re all ripe, all grapes of a particular variety display the same final color. That’s why you can’t buy or eat Rainbow Grapes, but you could certainly witness their beautiful transformation.
最後一旦所有的葡萄都成熟了，無論是哪個品種的葡萄，都會變成那種特定葡萄的顏色。這也是爲什麼人們買不到或者吃不着彩虹葡萄，不過人們還是可以見證葡萄顏色變化的美麗過程的。

However, that doesn’t seem to be stopping people from trying to actually sell rainbow grape seeds for a profit. The photos circulating online don’t help things much either, especially when they come with descriptions like ‘unique grape variety’ or ‘hybrid grapes’. And to make things even worse, most of these unscupulous vendors use digitally-altered images of rainbow grapes, like the ones originally posted on , as part of a Photoshop contest.
然而，仍然有人爲了謀利在售賣所謂的彩虹葡萄的種子。所以網上流傳的圖片其實並未產生好的效果，尤其是當這些圖片被配上“獨特的葡萄品種”或者“雜交葡萄”等說明文字的時候。更糟糕的是，大多數無良商販使用的都是被PS過的彩虹葡萄圖片，比如最先出自於這個網站的那組圖片，而這些圖片是上傳者爲了參加PS大賽而製作的。
