Proper way to recolour new bullets?

I’ve been trying to turn them darker manually, since Dark Reader now inverts them to white automatically, but there seem to be new fills popping up and overlaying, even if I override the default one with a Custom CSS.
The relevant rules I’ve found so far:

.rem-bullet__core { /* this is the bullet's center colour */
	fill: currentColor; /* presumably, this is what confuses Dark Reader */
.rem-bullet--hidden-children .rem-bullet__ring { /* this is the static outer bullet when it has folded children */
    fill: #d8d8e4;
.rem-bullet__ring { /* this is the outer colour when hovering the bullet */
    fill: transparent; /* also quite a problem for automatic solutions */
