Font / text colour (to transparent background)

Hi,

My website is white, so I changed the background from dark into transparent.

But now the name of the language is grey and not so good visible.
I would like to change it to black, but I didn’t find sg like font color or text color.

Please write the css to me if it’s available 🙂

Thank you,
Tamara

(Maybe somebody wants to use the CSS for the transparent floater background:
#trp-floater-ls {
background-color:transparent;
}
