Yeah- if I remember rightly, Toelle's analysis was that the red pigment was vermillion. Vermillion ain't just a color name, it's a particular pigment, and being a mercury compound, the real thing is rather hard to come by these days. It's a pretty bright color and depending on the light can be an eye-gouging red with a subtle orangy-pink glow. I still have a tube of the real stuff from decades ago...somewhere around here.
Also, I remember that it was indeed some rough soot embedded on top of the red that gave the sample its overall dark look. I believe he surmised that this sample came from a part of the airplane that was particulaly exposed to engine gunk.
