Warped blocks are the wrong color (brown) on maps

Hi there!

I tested this in my own world, and can't reproduce this. It looks like you're using some datapacks. If you are using any datapacks or resource packs, try removing them, and see if the issue persists.

Also, have you opened this world in any snapshots? There were lots of issues with maps during the snapshots. If you have, which snapshots were they?

I'm attaching a screenshot showing my results when testing this bug.

Also check if updating the map fixes the issue.
