The problem is: what blues were being used?
Robert Louis Stevenson was building his home on Samoa. He wrote his friend, the artist Paul Gauguin, who was living on Tahiti, “For a little workroom of my own in the back, I should like rather to see some patterns of unglossy -well, I’ll be hanged if I can describe this red- it’s not Turkish and it’s not Roman and it’s not Indian, but it seems rather to partake of the two last, and yet it can’t be either of them because it ought to be able to go with vermilion.” Thus description of colors by name will fail, at least we have various swatch systems to help -with FS595 being the easiest to obtain for those of us with a small billfold.
