If you must use a flatbed scanner, then use vuescan as the program to control the scanner.
With the professional version it it quite simple to find the correct color for the scan. Scan part of a negative that has no information (an empty frame or the space between to frames) and use that to set the black level.
Lock the exposure, scan again and set the color correction you like.
Then you can lock the settings and most likely the color correction will work for the whole roll.

Another great advantage of vuescan is that it will let you store a raw linear file with no color correction as a 16bit Tiff file, that you can then take to whatever image editor you use, and do the color balance there.
Never trust auto-correction, auto color or auto-anything.
Scanning the prints will not yield as great results as scanning a negative.
If you have a lot of negatives to scan consider getting a macro lens and a copy stand and a lightbox. You can digitize images much faster with a camera and at a much higher resoultion than with a flatbed scanner.
Save the images as raw files and color correct them in bulk using whatever raw conversion app you like (lightroom, darktable, rawtherappee, etc) where you can do proper color balancing.
