Le Ballon Rouge

Lovely film that.  But today's monoMonday challenge set by davidc is Diamond?  Do you see it hiding there?  A diamond in the rough; but it is too windy to be playing cards outside in the rough grass.  Am I sorry for the select colour treatment?  Probably the first and last time I will do it.  So this is bichrome?  Trichrome?

Edit:  Albert Lamorisse  made an earlier film:  White Mane (Crin blanc: Le cheval sauvage) that introduced me to the Camargue.
