Step 3: Correct color
On IE10 I observed hard to read button text when making a change. See screenshots.
Steps to reproduce:
- Go to http://en.wikipedia.beta.wmflabs.org/wiki/Main_Page?debug=true
- Open ULS through cog
- Select Display (screenshot "Step 3")
- Select the second button with the language name (screenshot "Step 4")
The background color of the button changes to "silver" and makes it hard to read.
