Trying to identify 1970s kids show with solid blue eyed humanoid called Sky (?)

Question

In the early '70s I saw a kid's show where the title sequence showed a presumably crash-landed humanoid unconscious in a forest, slowly covered with falling leaves. In the first episode he is found by a boy or teenager, who I think calls him "Sky", because the alien's eyes are solid, startling blue - no pupil, iris or white. I suspect it was on BBC1. Can anyone help me with any details about this?

Oh, oops. Just found it through Wikipedia:
