>>4329423Color balance is affected a lot by the scan, and in negative film there is no correct setting so it's "artistic choice" on the part of the intern working at the lab that day. Looks like there is some NR in the scan too so I dunno if they're the best quality.
But there are limits to what can be accomplished, which depend on the film, developing and exposure. I would check the negatives to see if they're particularly dense or thin since the colors do seem a bit off there.
