At the same time we have the Douglas Grey which dates from at least 1842 which is the Douglas pattern but black and grey "colors" and Douglas is from the gaelic Dhub: black & glas:grey/water which could be interpreted that the black and grey might, I stress might, have been taken from the meanings of the words that make up the name. I personally doubt it but it is interesting that the colors of the Douglas grey match the meaning of the words that make up the name.
