The A6500 settings do indeed provide a better color for the A7S, just finished a small project and even tho there is a difference in color between the S1 and S2 its easy to correct in post.
@zuberman - Im getting that same red-to-orange glow in the car's stoplights on my A7S and A7S ii plus some orange-to-lime-green in some instances. Would be nice if we could get rid of those without messing the rest of the color.
 

The a7s doesnt have as much of a yellow cast as the a7sii, so dialing down the white balance matrix settings Andrew provided (matrix not white balance) might make it warmer. Also if your using s-gmaut as a substitute on the a7s, use the V2 version for the a6500.
