so is there a way to trigger an item_found silently on map change to force the yellow color to be used?

[DJ Tsunami]

Well the only way to silently trigger an event is by setting dontBroadcast to true, so try that. But I hear it needs to be broadcast for the clients to pick up the color change.

If players don't see this text broadcasted by the item_found event, they won't see the colour.
