Is it true or a recent fallacy that Father Christmas has only been dressed in red since being depicted that way in a Coca-Cola advertisement?
If so, he was American and probably called 'Santa' rather than 'Farther Christmas', as if being unaware that Santa means Saint (and yes, I do know it comes from Saint Nicholas, or maybe Saint Peter for people whose ancestors were from a different bit of Europe).

I do like a nice dark green Father Christmas, myself.
