After upgrading to 2021.3, I could not change the accent color from Fluent Theme anymore.
I've checked and noticed that the problem is with the MaterialAssist, that is not using the color set in the AccentColor of the FluentPalette.
My code has always been like this:
FluentPalette.Palette.AccentColor = (Color)dicEntry.Value;
And it has always worked (I have an old version with the older components and it still works), but now I don't know what to do to fix it.
