Hello

As you can see, I am using a .ctb Plot Style.

I have "display plot styles" in my layout Plot Settings. 

When I make a line directly on the layout page, the plot style is displayed correctly.

When I make a viewport on the same page, it will not display my plot styles in the layout tab. Even after regenall.

The remain the color that the layer is labeled. 

It seems I can use a true color on the layer and change the colors of the displayed or printed lines, but that is not the purpose of the .ctb.  

I am aware that .stb is preferred, however I am working with a lot of legacy .ctb files. 

Please advise.
