Does "invert" icon exist? about material-design-iconic-font

[kuncevic]

For my understanding .md-inverse {color: white;} is not build in css class isn't it?

This is a font. If you want the md-report-problem-icon in white, rather than black, it's a matter of styling it, just as you would any other text...

 .md-report-problem {
      color: white;
 }

@emiloberg, thanks for answer - you are totally right.
But for topic reason i recommended to use class .md-inverse {color: white;} and add it for all icons that should be white.

.md-inverse {color: white;} @zavoloklom You just answered you own question, add that to your sS and any font you add the class md-inverse will be white. You could add as many as you want for example:
.md-blue {color: blue;} etc, etc
