Inverted selection colors

Sun, 08 Aug 2010 03:10:26 -0700

Not sure about the exact rules governing this, but usually when the colors of a text being selected are "inverted" the selection colors (background/foreground) get inverted too, as in (see sample attached): 

<p>
...</p>

<p style="background: Highlight; color: HighlightText;">
...</p>

<p style="background: white; color: black;">
...</p>

<p style="background: black; color: white;">
...</p>
I find Mozilla's behavior of choosing whether to use inverted selection colors suboptimal compared to other browsers, like Opera 10.60 and Safari 5, IE 6 (I'm trying this on Windows XP), for example. Going to <http://blog.mozilla.com/about_mozilla>:

Then selecting some of the text I hardly see the selection:

It appears o.k. in Opera:

Looking into it I see:

  <body>
    <div id="rap">
      <div id="top">
        ...

And the following CSS rules applied:

body {
  background: #333 url(img/bodybg.png) repeat-x fixed top center;
}
#top {
  background: url(img/contentbg.gif) repeat-y top center;
}
Removing the background image (using Firebug, DOM Inspector, a bookmarklet) from the div#top makes this clearer:

Seems Mozilla is picking the selection colors based on the guessed background color which doesn't seem as reliable (background images could not easily be taken into account). I think Mozilla should just be using the color of the text when determining the selection colors, as the other browsers appear to do.
My Bugzilla search revealed couple releated, but not same issues on Linux and Mac platforms:
(Linux) selection highlights not visible in "inverse" high-contrast themes <https://bugzilla.mozilla.org/show_bug.cgi?id=237534>
(Mac) Selected text highlight color does not contrast with foreground or background color <https://bugzilla.mozilla.org/show_bug.cgi?id=445258> 

Is anyone aware of this filled before, at least on Windows?
