Red Graphite theme is available via Community Theme settings. Go to Settings (cog wheel at the bottom left panel) > Appearance > Themes (click on Manage) > Red Graphite you have to scroll or search for Red Graphite
No, sorry, I have the theme installed but it is not showing the correct fonts. On the GitHub page for the theme, it tells me to enable Custom CSS. I can’t find this setting — I can’t figure out how to enable Custom CSS. That’s where I am stuck.
maybe u can share a sample note u have to see how it looks like. how is it u say that it is not showing the correct fonts. also note i notice that the theme seems to be not update for awhile, there has been material changes on how theme are structured in Nov/Dec 2021 (i.e. there’s live preview and obsidian.css no longer applicable, css snippet folder ([vault]/.obsidian/snippets) is used instead).
I’ve attached a sample note at the bottom of this message. You can see that the fonts are different.
You mentioned that there were changes in how themes are structured since Nov/Dec 2021, and also that the theme has not been updated for a while. I bet that is what is happening.
I found the css file for Red Graphite in [vault]/.obsidian/themes/Red Graphite.css. I tried copying that into [vault]/.obsidian/themes/snippets and turning it on, but that didn’t change the fonts.
