Different color for backlinks in Graphy view

Things I have tried

What I’m trying to do

Hi friends, I am just wondering if there are any existing plug-ins or CSS snippets that could only highlight the backlinks page/node in different colors.

The scenario is I have a lot of pages that mentioned the same page in my OB. I want to see these pages, which have never been mentioned by other pages, in a different color from the graph view.
By doing so, I could easily understand the function of these pages - they are only the backlinks of a main page.
Please let me know. Thanks

I have found a solution by using different tags and grouping them in graph views.
Thanks

BTW, any chance to enlarge the arrow size in graph view?
