I came across a note in our docs that employs several words in `backticks`. The grey background of the note blends in with the backtick color, making the text somewhat difficult to read. See the screenshot for an example:

## Proposal
<!-- Further specifics for how can we solve the problem. -->
It would be nice if we could alter the backtick color when used inside of a note, or slightly change the default backtick color so that there's more contrast when used inside of a note.
