Chrysler had some really ugly greens at that time, and sometimes it seems that most of the Mopars from that era are painted an ugly green. But, the green on your Dart appears to be the Spring Green Metallic (bright green) that came out mid year 69 for only the 69 model year. Its actually a very nice shade of green and is rather rare and desirable. You need to find a shiny restored example in that color to show your wife before making the final decision on a color change.
