Errors with colours

After the recent update (I’m on Obsidian 1.13.4) I’ve noticed that custom colours have been acting strangely. At first I thought it was just the Callout Manager plugin, but it seems like the same thing is happening for Highlightr, too. I’m not sure what the issue is, or if they’re even related, but they happened at the same time. I’ve tried both plugins in a Sandbox vault, with the same result:

This callout should be blue, but instead it looks like this:

And in highlightr:

I can’t edit the colours (through this menu), or add more, because the colour won’t render (which, from memory, it needs to in order to add more colours). Highlights still work in the markdown, though.

I’m not sure if this is a setting that I need to change, or if both plugins need to be updated to accommodate the Obsidian update. If someone could explain, I’d appreciate it. :blush:

Have a look here for callout manager:

edit: Seems it was updated shortly after I posted the above. Yay!
