there are many programs for adjusting pictures...almost any can help, but when it is mostly color balance, it can be tedious to get it 'just' right. Since you seem to have scanned them, perhaps several of us could try some tricks.I am not a 'wizard' exactly, but if you want to email me one, I'll try several things.

I'll bet there are others who do this regularly...maybe between us we could improve them to acceptability.

I have at least 6 different programs to experiment with, but it is a very similar process in most of them to change red/green/cyan balance.
