XF 2.0 Change Topic Title For Single Thread

[kingdomkz]

I did locate another tutorial here related to this topic, but I didn't see any information about how to customize a "specific value" in regard to a class in the extra.less template, I found a few bits of information online, but nothing has worked so far. I'm trying to color a specific ".p-title-value" to blue through an [attribute=value] method, but I haven't figured out what the "attribute" is supposed to be. I mostly referred to this:

https://css-tricks.com/almanac/selectors/a/attribute/

.module[attribute="value"] {
  /* style rules here */
}

Here's what I have so far:

.p-title-value [attribute="The Usual"] {
    color: #33e6ff;
}

I know it's not supposed to say "attribute", but I can't quite figure out what "attribute" is supposed to be. Any help would be appreciated!
