A study of patterned bricks shows that not all English buildings were of one color. Exteriors and interiors used limewashes as well as different colors of bricks (or even glazed bricks!) to enliven the surface.
"We rarely experience the effect of coloured limewashes on major buildings. The tradition died out before the age of colour photography could record it convincingly: as the saying has it, out of sight is out of mind. Yet there exists copious documentation for coloured limewashes..."
Nine examples of English buildings with colored brick patterns are shown, along with an explanation of how the patterns were made and glazing was accomplished. (photos)
