Hi Eran,

I think I found the reason of the problem and I am working on the fix for it. There are missing implementation of the defaults definition of css classes in in file: https://trac.webkit.org/browser/webkit/trunk/Source/WebCore/css/mediaControls.css

In mean time you can try some workarounds for your problem:
1. if you can modify the WebVTT files you can add there css classes for missing defaults, e.g.:
STYLE
::cue(.magenta) {
  color: rgba(255,0,255,1);
}

2. if you can't modify the WebVTT files but you can modify the css in the HTML site on which your stream is used then you can also do this, e.g.:
::cue(.magenta) {
  color: rgba(255,0,255,1);
}


You can specify in such way any classes you would like to use in your WebVTT files.

In the meantime I will try to push my fix and cross fingers for positive review:)
