Often when scanning it's not only the white balance that needs attention. In this case the white balance is fine but the mid greys and darker have a blue cold colour ting. The leaves are also meant to have more browns.
Epson software is pretty bad when it comes to colour balance. It does more of a white balance then an actual colour balance. Using an image in this thread as an example I added a mid black correction of the image. This type of colour balance is important for films like the new Kodak Ektar.
Here I have used the pavement to re-balance the colour balance.
