Conditional text color changes to column data

I remember something about this a few years ago, but can't seem to find the post through searching.

As I recall, there is a way to script certain column results to display in a different text color to help highlight items that need closer attention. With the bitrate column, I'd like to show all bitrates 128 and below in red so they stand out and can be avoided.

It would be easy to make an extra column that contained a script that allowed only bitrates of 128 and lower to show up (those with higher bitrates would simply be left empty.) However, I already have too many columns and adding another one that would be mostly 'empty' seems sorta silly.

Any suggestions on how to bring color to some parts of my results panel?

Thanks in advance.
