rootboy,
The 1970-1973 US Gitane catalog calls the color Match Blue.
During the foil decal ear from 1968 to 1973, almost all of the "blue" candy apple or flamboyant colored bikes that came into the US were sort of a dark turquoise blue like the OP's bike.

Gitane also used a darker blue color that was called "racing blue" or French Blue???
They used this color form many years on the European models and also the US bikes starting in 1974.
Because these "candy apple" colors were dyed clear lacquer applied over a white, silver or gold base coat they varied depending on the paint layer thickness. The bike boom colors were also prone to fading.
I used mid 80's Gitane racing colors on my blue bikes from that era but I think more subdued colors would go better the OP's bike.
But... fashion is such a personal thing so who am I to say?
