Remembrance of Décor Past

In a deep dark corner of the barn I uncovered the half full pots of paint (and assorted tiles) that are left over from decorating but kept to deal with the unlikely event that a wall suffers some calamity that requires it to be partially repainted; this, of course, has never once happened, and even if it did how would I be able to match the shade of magnolia on the wall with the name on the tin, how to tell muffin from coffee cream or burnt biscuit from banana crumble, or any other exotic name dreamt up by the marketing men and women.
