4-2-stable: 5 runs, 5 assertions, 4 failures, 0 errors, 0 skips

• 4-2-stable and 5-0-stable seem to only update the column if you have a full object (where you don't use .select).
• 5-0-stable raises the NotImplementedError if you leave off color, updated_on, or updated_at, whereas 4-2-stable silently doesn't update the color value.
