When you see a question in Code Review with some CSS and hex color codes in it, it appears like a comment.
I think the syntax highlighter thinks that CSS uses python style comments i.e. print "2" #here is a comment.
It should be a different color.
Thanks.
The default syntax highlighter uses a "one size tries to fit all" approach, which will not always be successful. I have changed the setting for the css tag such that not the default highlighter, but the CSS-specific highlighter is used for questions with this tag (example).
In general, you can also manually specify which highlighter is to be used, by inserting
<!-- language: lang-css -->
right before the corresponding codeblock. See the syntax highlighting section in the editing help for details, and this answer on meta.so for a list of supported highlighters.
