Black titles in filters list jump out

[Dylan McCall]

As Harvest's design changed, I seem to have forgotten about the filters area :)
Currently, each filtergroup has a full black title. In other places, titles are styled quite differently to match with the regular content.
For example, on the landing page, the title is rgb(80,80,80) which fits smoothly with the regular body text of rgb(51, 51, 51).

The filtergroup titles are not clickable, and they are not important bits of content. Full black should be reserved for those cases.
