I didn't know about color tv rentals. In Romania (at least in the '60's) you could rent some electronics for events.
"Renault" 4... there where several in Romania too (seen them in Bucharest)
But I wonder, who made the picture tube for the French color tv sets. "Videcolor" as far as I found camed out only in 1971.
The Germans (West) also where intrested in exports. Never seen a French tv in Romania. Germans (East and West) yes. Plus Dutch "Philips". 'Telecolor' 3007 had sometimes "Videocolor" picture tubes (mine haves "Toshiba").
I guess since most people dind't had a color tv before 1973, French early color tvs are rare 
Here is that "Schneider":

But how come that most of those early French had such quite big screen for it's days.
