Changing default color palette for blocks?

Is it possible to change the default block background colors, ie not using tags?

I would like to change the “yellow” color on the right-click menu so that it produces an orange block. I don’t care what color shows up on the menu.

Try adding in file custom.css something like this:

* {
  --ls-highlight-color-yellow: orange;
