I sent a FB message to CyberSibes, but I know she's away right now. This is something maybe only someone older than me, and with an artistic bent, would know:
When I was a kid, I basically had just two "colors" of ink available beside black and indigo blue for my calligraphy pens. One was Allizaron Crimson, and the other was a "Lord SomethingorOther" Gray that had was an almost black with a blue tint when used thinly. Have you any idea what it was called, way back in the dark ages? Hoping this rings a bell for someone, at least!
