A few Jedi
did use red lightsabers - although those novels and comics stories are now 'Legends' - and I think these may have been before the concepts of 'bleeding' and other more modern portrayals of lightsaber construction?
Luke's red shoto, Leia's red saber
(though she may not technically been a Jedi at the time? I can't recall the details), Adi Gallia, Even Piell, Depa Billaba, Sharad Hett, his son A’Sharad Hett, Aayla Secura, Yaddle, and the Jedi shown in '
The Star Wars'
(2014 comic based on GL's 1974 1st draft of SW)...

I'd love to see a similar 'follow-up' comic based on Leigh Brackett's script for Empire Strikes Back.
There are probably other Jedi with red sabers too. I know this isn't probably what you meant - but I took it as an opportunity to post up a few cool old
(maybe long forgotten for some of us?) images of Jedi back in the earlier comics and novels etc when the colour of sabers didn't appear to signify anything in particular.
(At the start of this all... way back in the 1978 '
Splinter Of A Mind's Eye' novel, Vader had a blue lightsaber, and Luke could also alter the length of his saber.)
