We are on 3.2. The site uses essential theme. I'm wondering how to achieve a departmental logo appear on the course category index page (not a custom logo/icon for each category which I have already been able to via settings)? Each course category would have a unique departmental logo that appears in the top left corner of /course/index.php?categoryid=1,2, etc).
(As an aside in case it impacts the answer, I plan on using a different theme for each category, but basing it on the essential theme. Really all I'm trying to do is achieve a custom color palette for each category, based on the identical theme. Ultimately I would envision categories with forced themes of "essential-Eng dept", "essential-Hist dept" etc I'm working my way through the steps to duplicate a theme and apply it to the site)
