Gallery Bullets (White / Black)

Is there any way for the gallery bullets to change overlay color from white to black with each image background? On images that contain a lot of white, the white bullets are virtually undiscoverable and prevent users from browsing galleries.

Not possible. You can consider change background + line color, and change active color, I can give code if you share page url.

That's ok, thanks for offering but I suppose I'll simply remove images that don't work with this setup

This is not a solution but you might be able to get closer with something like the following CSS. I can't give you an exact code as I can't see your site.

.gallery-fullscreen-slideshow .gallery-fullscreen-slideshow-bullet-nav .gallery-fullscreen-slideshow-bullet {

  mix-blend-mode : exclusion;
  
  }

mix-blend-mode CSS property.

Let us know how it goes.
