How do I change color of links visited?

Use Textedit (should be in your main Applications folder): open a new document & choose Format - Make Plain Text (if that's not already set)

copy/paste the following into it

a:visited { color: red !important; }

then save it, with the extension .css : links.css for example.

Now go to Safari - Preferences - Advanced - Style Sheet and choose the file you saved.

Extensions like http://canisbos.com/quickstyle allow making changes per-site; also read http://www.w3schools.com/css/css_link.asp if you need more detail/options.

That worked for me.

However, my main concern was visited links when searching from Google. Not necessarily ALL links or places that I have ever clicked on, which is now what is happening.

Every single site and every single place I have ever clicked is purple now.

How do I specify to only switch to just when I am searching ?

Thank you!

I like the idea but I see Jennseay's point. For example, when I went to ABC and pulled down "All Shows", then selected "Castle", the color of the Castle link remained red even after I reloaded the page. On the plus side, you don't have to use red if that is too bright for you. You can change the color to whatever you like, and if you don't want to keep the change, just go back to "none selected" in style sheet.

The only fundamental requirement here is that you need to insert CSS code into sites you visit. (In this case, the CSS changes the link color. It can change almost anything else, though.)

You can do this in multiple ways. One is to add a Style Sheet to Safari in the settings. Another is to install the extension Stylish (http://sobolev.us/stylish/), which will let you add CSS to specific sites, all sites, classes of sites, etc. See the example below:

Worked for me, also. So simple. Saved the LINKS.CSS to Desktop, changed Safari Preferences as you directed, Bingo. And then I trashed the links.dss from the desktop and it still works. Many, many thanks.
