Opaque is the opposite of transparent. 
You mean more opaque, yes?

Yes!

Why not to make search box as default focus when in Overview, which not only increase visibility of search box but increase the usage of it. You get Overview by mostly moving mouse to the left-up corner after all, which means if you want to search something, you have to click search box at first.

Actually you don't, typing anything will move focus to the search box. Looks like we need to make this more obvious, if after three stable releases users still don't know about what I'd consider one of the most compelling shell features.

I think what you said just make my suggestion sensible, how could a user expect to find that (by accident? I have used gnome shell for the beginning of 3.0 release), that's completely different from most other cases or applications.

Hi gan lu. This sounds like a separate issue to me: we need to make the unfocused search box more distinct, irrespective of whether it is focused by default or not. Can you file another bug for your suggestion, please?

Thanks for your kindly reply, there is my new bug report: https://bugzilla.gnome.org/post_bug.cgi

First try

After playing a bit with the CSS, I've found out that increasing the label+icon brightness plays very well with different backgrounds.

I also tried with the background opacity, but it is quite its style makes it look weird (it starts from hard black to hard white). We could also use more colors maybe.

I've put some comparison screenshots there to avoid spamming on bugzilla: http://zzrough.free.fr/files/public/gnome-shell-686479/

sorry, I meant http://zzrough.free.fr/files/public/gnome-shell-686479-Overview-search-box-is-too-subtle/

Looks good, Stéphane! Could you try updating the outline/stroke color too?

I've added screenshots at the same address with "brighter" and "even brighter" stroke variants for background3. I think "brighter" is enough though, as with the "even brighter" one, you feel the field is focused or highlighted somehow.

I agree: "brighter" looks good. Can you attach a patch?

#searchEntry {} already exists (and you are actually modifying it!), add the border-color there.

Ho, of course, thanks: I did put it there because I thought the rules in-between would overwrite it, but these are only based on pseudo-selectors, so it's fine.

Oh sorry, missed the outstanding review. I'm happy with the patch if the designers are :-)

Thanks for the patch! This is much better.
