It was a rather complex custom mix using Cook's Blue #237 and a dab of St Giles Blue #280 with a few drops of All White #2005 in estate emulsion by Farrow & Ball. A professional painter versed in using these high caliber pigments can assist you in achieving just the right blue for your room. It took us a few batches to create the perfect blue I desired to contrast well with various deep and mid-tone browns found in wood grains, mohair, chintz and pendant.
