dash searchable dropdown foreground/background input color

I am trying to modify the foreground or background color used by a dash searchable Dropdown when a text is input to search in the list.

The input text is black which is almost impossible to read using a dark theme.

Through the css I am able to modify a lot of colors, example :

• the color of the text in the list is red doing :

  .Select-control, .Select, .Select-value-label, .Select-clear-zone { color: red; } or .Select-menu-outer {color: red; }

• the color of the background for the current value or Select ... if no value is blue doing :

  .Select--single > .Select-control .Select-value, .Select-placeholder { background-color: blue; }

• the color of the text for the already current value or Select ... if no value is green doing :

  .Select.has-value.Select--single > .Select-control .Select-value .Select-value-label, .Select.has-value.is-pseudo-focused.Select--single > .Select-control .Select-value .Select-value-label { color: green; }

• it it even possible to change the color of the text in the list to be purple when the mouse is inside the list area doing .Select-menu-outer div:hover { color: purple; }

But I cannot found a way to change the color of the input text or its background to search.

How to do through the css or using options (style) in the Python code defining the dash_core_components Dropdown?
