The color of the needles isn't a great indicator of age as there was a lot of variation over the years. But yes, generally the very light green is older and the almost black is newer. But what you need to look for are the tags or stamps. Every item has them. The jacket has it inside one of the chest pockets, the trousers inside the fly. For the cape it's found along the edging in small black print.
Roughly speaking from memory the 1st model snow suit was made 1960 to mid 1960s (1963??). If it has buttons that's all the ID you need to know the timeframe. If it has snaps and zippers, it's the 2nd model. I think all the capes were made early 1960s, but I could be mistaken about that.
