Change background of "Signature Permissions" in Templates

[Rlad78]

Does anyone know what template I'd have to look into to change the color of the signature permissions? Below are screenshots:



As you can see, it's transparent when I want to make the backgrounds a different color without using StyleVars. I need that section to be transparent for the forum text descriptions but not in these particular spots since the text is hard to read.

additional.css template:

.permissions{
  background: #hexcolor;
}
