Material colors too bright?

Hi everyone

I have a small material library, which I have previously used in Revit 2016, however when I use the materials in Revit 2017 they all seem a lot "brighter".
I have also noticed the same behavior with a material library from a supplier.
Does anyone have a clue as to why this is happening? It is the same library file, just loaded into two different versions of Revit.
Has it something to do with their change in rendering engine? And does anyone know how to adjust it? I think the color representation is harder when the selected color is brightened that much when rendered.

I realize that lightning might influence it, but I can't seem to wrap my head around, why there is such a difference between 2016 and 2017?

On a side note, I have also previously used the "Tint" option to change the color of a material with an image as texture (i.e. Wooden boards on the walls). However in 2017 the effect of the "Tint" option seems to be a lot less prominent.
Can anyone offer any suggestions on that as well?

Thank you all so much in advance.

I'VE GOT THE SAME ISSUE...

Same issue / Concern. Looking for insight as to not need to modify all materials using tint or brightness modifications...
