Wolf Rayets come in red..?

They shouldn't, but they do... in-game, Wolf-Rayets can have any temperature at all, right down to sub-brown-dwarf temperatures (at which point they assume a purple mien just as shown.)
Plotted on an HR diagram the in-game WR stars form a broad band which runs very loosely alongside and around the main sequence but is distinct from it. Don't ask me, I only fly here.

that is weird. no more can be said
If that indeed shows up as a WR, I'd wager it's a bug - this is exactly what brown dwarves look like. You sure it's not a companion brown dwarf in a system that contains a WR? Can you show us the system map?
As Jackie said, it's the low temperature that makes them look this way.
I found 2 WR stars in red and I went to check the cartographic records website because those 2 had low temperature and the record holder for the coldest WR star looked exactly the same.

Never saw a WR that looks like that.. nice find!

All Wolf-Rayet stars are extremely hot O-type stars. This particular one is dominated by carbon, so it's called a WC-type star. These get subdivided from WC4 (on the hot end, around 117,000 degrees Kelvin) through WC11 (on the cool end, around 22,000 degrees Kelvin). It's possible there could be cooler Wolf-Rayet stars, but these would still be very hot. You need to have broad emission lines of ionized carbon, nitrogen, oxygen or helium in a star's spectrum for it to be classified as a Wolf-Rayet star, and you only get these emission lines if the star is really hot. One of the coolest WC-type stars I know of, for instance, is M4-18. It's an WC11-class star, 22,000 degrees Kelvin, with a blue color like a B-class star.
