          no, it is only available in white or black

          How do the PDL 600 and 800 series product codes work?

          As a general rule of thumb -
          PDL items require PDL at the front of the code.
          600 series item codes start with 6.
          600 series switch codes start with 68.
          The number of switches fitted in the plate is the 3rd number in the code, 681 = single 600 series switch, 682 = double 600 series switch
          600 series socket codes start with 69.
          The 3rd digit in a socket code indicates the type of socket, 691 = single vertical socket, 692 = double vertical socket, 694 = single horizontal socket, 695 = double horizontal socket.
          Most codes require a colour code at the end, WH = white, BK = black.
          eg. To order a black double vertical switched socket the complete code would be PDL692BK.
          800 series (Modena) item codes start with 8 and follow the same format as above. (800 series items with Strato plates start with S8...)
          eg. An 800 series Modena double switch in white = PDL882WH, a Strato double horizontal switched socket in black = PDLS895BK 
          In both series metal cover plates are an extra option to be supplied separately, coded to fit the plate required, eg. 600 series single switch metal plate in Stainless Steel = PDL681MSS (M = Metal, BBZ = Brushed Bronze, PB = Polished Brass) Some plastic cover plates are available eg. PDL681CWH (C = Cover), PDL800PSCH (PS = Plastic Surround, CH = Champagne, there are 9 colour options in 800 series)
          Strato brushed aluminium plates also need BK or WH to decide the trim colour, eg. PDLS800CBABK or PDLS800CBAWH (C = Cover , BA = Brushed Aluminium)
          Module grids with covers are available in BK or WH, eg. PDL684VHWH (VH = vertical/horizontal since the grid is empty and module can be fitted either way), PDLS800GPSBK (GPS = Grid, Plate, & Surround).
          Grids without covers included are only available in Modena 800 series, PDL800G (horizontal) or PDL800GV (vertical)
          Refer for further details and options.
