Syntax highlighting is unreadable within "Tip" blocks when viewed in light mode

[sbddesign]

The syntax highlighting of <code> elements within a div.custom-block tip has white text with a light background, and can't be read without manually highlighting with the mouse cursor. I suggest a darker color for syntax highlights when they are contained in a tip block in light mode. Replicated in Brave and Firefox on macOS.

Fixed, I was using the wrong background color, not the light one Christoph proposed.

Thanks for spotting and reporting that, Stephen!
