Could you clarify exactly what you’re trying to do? In the language dropdown menu, it only shows the letters for the non-active language. Which bit are you trying to style differently?
If Dutch was selected, and you just want to make the “D” stand out, you should be able to click the text and set the color property e.g.
.wpml-ls-display {
color: red;
}

Hey, did you paste that selector somewhere, rather than using MT? If so, try using MT. MT should find a selector that only targets the single element you clicked. The .wpml-ls-display class is used for the other languages too I see now (on closer inspection).
But if you want another copy and paste, try updating the selector to this:
