[BUG] White font on light theme

[angiioh]

Describe the bug
I've noticed there are certain elements that are basically white text on the off-white background in light mode. (I'm specifically using the purple variant)

To Reproduce
Steps to reproduce the behavior:

1. Enable light mode
2. Go to a channel where you haven't read anything. You'll have the "mark as read" banner at the top, but the text is in white.
3. Go to any of the categories under BetterDiscord in the settings panel. You'll see the title is white as well.
4. Also noticed it with the icons for formatting from the plugin BetterFormattingRedux. I don't expect support for that, but maybe that info is useful?
