1531 doesn't - it was given a second repaint last autumn when it went for internal refurbishment, so matches the rest of the refurbished examples at Durham.
And the reason 1513-23 do is down to them having Bonded Glazing rather than Gasket as per the rest of the Pulsars - hence retaining the black.
