I watched it a long time ago. I presume it was aired in 80s or 70s.
Facts: The main characters are humanoid beings. Male and female, and very similar looking to each other. I know they could fly by some device that looked like a board, and that they were emotionally involved with each other.
They had an odd look: tall faces and no hair at all, although I'm not certain about the female character. Both had armor on them that was tightly fit to their bodies, and was blue-grayish colored. I'm not sure, but I believe they spoke French.
That's all I can recall about it... Except that the environment was like blue-grayish also, SF buildings etc. Not quite sure they flew over some watery areas... I've been searching the net for days and more, but have found nothing. Hope someone here can point me in the right direction.
