Here is a website that shows the '69 colors. Looks too dark for Lime Gold, but who knows. To me, I would think it is Black Jade. How about Anti-establish Mint?
1969 Boss 429 Mustangs were available in five colors: Wimbledon White, Royal Maroon, Raven Black, Black Jade, and Candy Apple Red. 1970 versions were painted Grabber Blue, Grabber Green, Grabber Orange, Calypso Coral and Pastel Blue. All 1970 Boss 429s came with a gloss black painted hood scoop.
Now, since you can't do your own homework....GIMME YOUR LUNCH MONEY!!!!!!!!!!
that is definitely black jade, it just looks a little different because of the bright sunlight on it. that color really doesn't photograph very well either.
