We found this fine example of weathered and patinated Norfolk Bog Door Blue on an old sliding door on a tractor shed while we were out walking the two terriers.
Now they go on about patination and character on the Antiques Road Show but we reckon the old barn doors, window frames, agricultural equipment and shutters in Norfolk have a distinct edge.
Farrow & Ball or Little Greene ought to be immortalising this colour on their swatch cards along with the usual Picture Gallery Red, White Lead, Slaked Lime and Blue Verditer.
Blue Verditer? I wouldn't paint my combine or barn door with that colour. Or the privy for that matter.
Norfolk Bog Door Blue rules.
