While working with a client today I noticed how filmic significantly shifts colors.

Besides the obvious different highlight pattern the color of the object shifted to green.

Any idea if this can be prevented? Otherwise I have to HSL fix each color to a key color input like I do below.

AFAIK Filmic doesnt shift colors.
Actually desaturates highlight to prevent the classic shift in highlights that you’ve noticed in “default”.
The shift in default is due to reaching “top” value of one or two among Red, Green or Blue values and impossibility to go higher, like the other values do.
