Subject: [PATCH] Fix colored view display when all list items are removed

When comparing two lists where all items are removed (t2 becomes an empty list),
the colored view would display an empty list [] instead of showing the removed
items in red.

The bug occurred because `_colorize_json()` returned '[]' immediately if the
list was empty, without checking for items that were removed and should be
displayed.

Fix: Check for removed items before returning empty list representation.

Added tests:
- test_colored_view_list_all_items_removed
- test_colored_compact_view_list_all_items_removed
