What issue is that in the American Marvel run? I’d bet the interior art is more accurate.
The extra covers needed for the weekly may also have been rush jobs.
It’s from a story called The Day After the Death Star and it was made specifically for Star Wars Weekly in the UK. It was released in the US a year later with colour as a Marvel Illustrated Books. Both the cover and the interior art was done by Carmine Infantino.
And no, he does look exactly like that in the interior art.
It’s hard to say what colours he was supposed to be though. The Star Wars Weekly comics didn’t have colours, and the coloured American release one year later gave him a different, but still pretty weird, colour scheme;
(Honestly the largest picture I could find online.)
EDIT:
Infantino drew a TIE-pilot that looked very similar in a previous issue (made for a US release);
The design is similar, but he’s wearing a black outfit which at least makes him look more like a proper TIE-pilot. However, we never see him from the front, so it’s hard to say what Infantino imagined.

However, he did also draw the cover art, in which the TIE-pilot look pretty much the same as he did in the Star Wars Weekly story. (The colourist, however made him look even crazier on the cover. Here he’s red and blue.)
