Film doesn't necessarily match the color response of the eye any more than digital sensors do. Fujifilm's Velvia film was renowned for extreme saturation, not accurate color reproduction. And optical viewfinders don't take into account exposure length either, so they won't give an accurate view of long exposure shots.
If you shoot raw you can always tweak the color balance in post-production anyway.
"And optical viewfinders don't take into account exposure length either"
The Minolta X700 does do that via a secondary faux-shutter mechanism and a light sensor. If you actually bothered to have a battery installed (which dies after about 8 shots,) the tiny auto-exposure sensor inside would take over and the faux secondary shutter would move out of the way.
The shutter in an X700 is timed electronically and won't work without battery power, a common fault occurs when one tiny capacitor in the timing mechanism fails, preventing the shutter from releasing.
I have no idea what the faux shutter is because the camera had a fairly conventional horizontal fabric shutter. The actual innovatation is with the closed-loop AE mode where the camera will account for a faulty aperture or more importantly, non-TTL flash by measuring light reflected off the film in real time.
