Google Chrome pinned tab highlight unread [closed]
This glow notification effect happens when the tab's title is changed.
To see, create an HTML file with some Javascript that changes its title after a moment, like:
setTimeout(function() { window.document.title = "New title!";}, 3000);Open it, pin it, then change to a different tab. After the 3 seconds, the pinned tab should glow.
Firefox 4 also does this.
Oh, actually read what you were trying to do now. Don't think you can change the colour, no.
You could change your theme (here) so the existing highlight is more obvious. It's a white glow, so you could (for example) use the 'Greyscale' theme.
I tried it and it is better; though a background flash / colour change would be much better than the light highlight IMHO.
