I have a pdf document with a few comments and annotations, presumably inserted by using Adobe Professional.  There are icons in the text which open up and show the actual annotation when I click on them.  That works rather nicely.  However, these icons are small and yellow, which makes them really hard to see on the usual white background.  Linux Acroread renders the same icons in blue, which is much better.

I'll attach two screenshots showing the issue.  I'd rather not post the file in public, but I'll happily send it to anybody who's interested.

Reproducible: Always
