SharePoint Online Create an Individual List / Library Themes

I have a group of users who have multiple document libraries and lists in each site of their site collection and who wish to differentiate libraries / lists from one site. Is there a way to change the accent color by list or by document library?

Example: There are 3 custom lists and a list must be red, green and yellow.

As far as I know, this is not possible with Powershell or SharePoint Designer because lists and libraries all inherit their style from the main page, but I hope someone will have found the way to the make it work.
