Meaning, "Hares are grey and so they should be called 'grey ones'?"
That's speculation, not evidence. Hares also have conspicuously long
ears and hind legs, they move by leaping, etc., so names like 'eared
one', 'longlegs', 'jumper' etc. would all be equally natural (assuming
that PIE animal names should be semantically transparent, which is not
necessarily the case).
