VP Color does not display in Sheet / Viewport

Hi All, 

I have set up color codes for layers in model space but want to override all these in the Sheet to be black. 

For that I read the DraftSight Blog Post that deals with the topic and used VP Colors.

I can pick colors in the layer manager in the sheet but they do not change colors. 

There was a suggestion here that the profile.xml file in AppData needs to be changed in order to reset settings , that did not help though. 

Can anyone help ? How do I differenciate colors in model space when I want to have them all black in the sheet ? 

I am using DS Premium 2026 

Thank you !
