Those Impulse Red/Black labels of the late 60s sound pretty nice ! I have a couple of Pharoah Sanders on that imprint..
They do sound very good, and you can get them for less money than the black/orange originals. I have a handful of Coltrane LPs on the black/red Impulse! label. A few have the Van Gelder deadwax imprint (my John Coltrane & Johnny Hartman and A Love Supreme), and a few don't (the Ellington/Coltrane one, and Coltrane). But they all sound really sweet in that trademarked analog way. The Love Supreme, in particular, which is close to NM condition, is one of my most prized jazz LPs. I think I'll play that one tonight!
