Can we get paint that matches the original wall colour?

If you need to match paint that is the original Galliard-applied ivory-type wall colour, it is Crown Trade Vinyl Matt Emulsion ‘Soft White’ or Dulux Trade Vinyl Matt Emulsion ‘Gardinea’. (They are the same colour.)

If these companies have changed the names of the paints, as they are inclined to do from time to time, the ‘standard colour number’ that should enable any paint selling shop with a mixer to match it is: BS 10-B-15. (As seen in the middle of this web page.)
