Change default background color of md-slider of Angular Material

Question

I am using md-slider of Angular Material version 2.0.0-beta.8

I have selected the indigo-pink theme and imported it in

Answer 1

Using color="primary" is just to set it to one of it's default themes. Only way to change the background-color as of now is,

/deep/.mat-accent .mat-slider-thumb, 
/deep/.mat-accent .mat-slider-thumb-label,
/deep/.mat-accent .mat-slider-track-fill {
    background-color: #128CB0;
}

Does anyone here know how to change the color of the text in the thumb-label though? Adding color: #fffff within the same css does not seem to help, it's still using black as the color.
