Do I need to reconfigure materials for unity 2017?

Hey all. I just loaded a Unity 5 project to Unity 2017 and now my GUIskin materials have changed color. Is there any configuration I need to add to get these materials to look the same in Unity 2017?


It looks the same as it did before if I open it in Affinity Designer.

I posted this on the answers community but had no responses

I converted the file to a png and that fixed the issue.
