I got mine out and compared her hair to the dollyhair colours I have here, too. I compared them in artificial "daylight" (one, that makes you wide awake and gets out colours most truly on pics).
The closest match would be Lemon Drop+Mermaid, if you ask me. In fact, these two do match pretty much perfectly.
Both Golden Delicious and Atomic Turquoise would be darker than what I see on my greek Sunbeam and Lemonade is a tad too light.
