I don't know what could be so different about the color settings for safari vs. IE 11 but I can't make out any of the dark shaded % areas. Its like the offset colors for the digits isn't happening or lacks a proper brightness control to make them visible.

Seems like your safari version is ignoring it?
OK better run the check across all the browsers I can test against ...
Checking menus and block page colours:
Windows:
FireFox 33.0.3 - OK (and 12.0 and 8.1 - it upgraded twice when I checked the version
)
Chrome 38.0 - OK
IE8 (WinXP) - Menus OK - Blocks background OK but font colour all black
Safari 5.1.7 - OK
Linux:
FireFox 32.0 - OK
Chrome 38.0 - OK
Android:
Chrome - OK
FireFox - OK
Opera - OK
Safari - OK Default Browser - OK
(the default browser in my Samsung GalaxyS3 reports itself to web sites as Safari)
Edit: but it seems it isn't Safari but most likely some Mozilla derivative
N.B. I don't test all versions - those are the versions I currently have installed on each device
Seems like IE8 and your browser both ignore the font setting.
Sigh - stupid browsers
I imagine that's simply a case of using a css class for the font will fix that one - I'll do that later.
Edit: oh on closer examination it might be the colours on those 2 are not getting it right ... anyway I'll look into it on IE8 and that will probably fix it for you also.
