Put light grey shading for level 1 heading in TOC

[frankximus]

Hey guys,



I've experienced a pretty strange issue here.

I'm working towards building a table of content, with slight shading for level 1 headings, however just can't find any solution to this.

I have a document in hand with such shading, and when comparing this document with a clean template, the only difference is in the "modify" section, it shows as "pattern- clear" with a RGB info. But I just can't edit the standard template for it to inlcude such a shading.

Can anyone please help?

Thanks
