That wasn't the point. The tests proved that as soon as O-ring smoke
encounters gaseous hydrogen, the color black (never seen *prior* to
that point) is rendered invisible.

Consider this. How long after t+59 seconds should we see black smoke
from a resumed O-ring burnthrough, assuming no hydrogen leak nearby?
Would you say until five or ten seconds after fireball exit? If not,
what produces the black smoke seen in the flare at that late point?
(See, for example, E207 photos at <www.mission51l.com/apreview.htm>.)

In 1997, I performed rudimentary spectral inversion on a post-X photo
of that blackened flare (taken from camera E201). I tried the inversion
because the E201 FOIA film has an unusual blue hue throughout. I used
Adobe Photoshop, after a digital conversion. I printed both the before
and after frames, with a cheap color printer.

I have a local friend who is extremely busy with seasonal work right
now, in addition to his regular job. When he has more time, he can scan
both copies for proof here.

Spectral inversion shows the normal booster exhaust (the contrail) as a
beautiful dark blue (or indigo). It will come as a big surprise to you,
but the flare shows up as black; i.e., there are two distinct colors --
a black flare, on a contrail background of dark blue.

Furthermore, NASA staunchly refused to release even *one* original 70
mm film frame to Kodak Laboratories in New York, for a *professional*
spectral analysis. (NASA's 70 mm film was designed for Kodak's spectral
analysis, by the way.)

Since you assumed, did you consider the possibility that NASA showed
you only what they wanted you to see, in the form they wanted you to
see it? Check out:
