Subtitles on the main page are not contrasted enough

Hi, thanks for your hard work 😊

Here's some UX / accessibility feedback.

Grey subtitles (main page, second pane) are not contrasted enough, following Mozilla's accessibility guidelines.

I suggest to use the color #5e4f3a, already used on the first pane for the search warning, below the search box.

This also applies to the orange links, below those subtitles, so using a brighter background might help too.

Thanks!
