How can I change the color of 'sold out' text on my website?

Hi,

I have tired using

}
  span.badge.badge--bottom-left.color-inverse {
    background: #ffcfcf; //Controls Main Background Color
    border-color: #ffcfcf; //Controls Border Color
    color: red; //Controls Text Color
}

To change the colour of the sold out text however this hasn’t worked.

can someone please help. I only want to change the colour of the sold out text.
