[BUG] - dark red in dark mode is hard to read

[mprather]

Description

This is minor appearance issue.
When a browser is set to use dark mode, the text in the oml spec can be quite hard to read.
Users that experience color-blindness probably have a hard time with dark red on black combo as well.

Expected Behavior

media selector for dark mode needs some adjustment to make it easier to read.

I tried adding the media selector, but not sure it works. Can you test it and let me know?
