Anyone know why the '2D tile palette background' color setting doesn't seem to work?

Just trying to figure out if this is a bug or something on my end. Here’s a screenshot:

The new colors will be applied only when you refresh the Tile Palette window.

After selecting color, switch focus to the Tile Palette window and pan your mouse over the main view. That should refresh it and apply new colors.
