There seems to be a decent LUT for 5247, maybe try it out and see how it fares. Or I just might myself.

I very much like the direction it’s heading, a pop feel with vibrant colors. I think Lando’s outfit in the film is a great place to look for that inspiration haha.
EDIT: I think focusing on the primary colors and maybe shifting colors to align more with the primaries, would really complement the elements already in the film nicely! Red (the Maw, Crimson Dawn), Yellow (Kessel, Lando clothes), and Blue (Vandor, Han’s stolen landspeeder, hyperspace).
