It certainly looks rust red like the video you linked to.

Good call.

I've been looking at videos and this one and the PEPCON are the only two I've seen that have that coloring. Apparently they're saying it was ammonium nitrate now, which was also present at the PEPCON explosion. Maybe it's the nitrate that makes the distinct color? Oxidation of the aluminum would be white, so that's not it.

I've seen chemical fires with that coloring before but can't find any demonstrative videos. Petroleum makes black smoke, wood and paper make grey, and chemicals make all sorts of colors. Now I'm curious about that color and what it tells us is similar between these two explosions.

This is interesting info.

More questions than answers. Thanks for sharing this.
