Is it possible to make a black and white Yandex map, but so that the balloon and the label remain in color?

Question

css

I did it simply through Css grayscale, but then everything becomes black and white. Is it possible to somehow access the API to do this, I'm flipping through the dock and I can't find it.
Invented via CSS Write something like:

#map ymaps.ymaps-2-1-45-balloon-pane,
#map ymaps.ymaps-2-1-45-balloon-pane ymaps,		
#map ymaps.ymaps-2-1-45-inner-panes,		
#map ymaps.ymaps-2-1-45-places-pane,		
#map ymaps.ymaps-2-1-45-places-pane ymaps,		
#map ymaps.ymaps-2-1-45-map		{
  -webkit-filter: none;
  -moz-filter: none;
  -ms-filter: none;
  -o-filter: none;
  filter: none;
  filter: none;
}

But I'm afraid that Yandex may suddenly change classes or something else, and in general this is probably not very correct. Tell me, how do you get out of this situation?

Answer 1

There is no option to make the map black and white. Generally speaking, this is prohibited by the PS.
