It doesn't take too much impurity mixed in to radiate color light an night.
After the Rocket takes off, the trail could be lit from the ground. Like a
wick burning up into the sky lighting various impurities. Haven't seen one
yet, so I'm withhold judgement wrt solid vs Hydrogen fireworks.
Makes me want see how cool the flame is. Build a campfire with a Hydrogen
Flame in the Middle. After a long day/night of Hydrogen FireWorks, make a
video with a Broom and see how well it works.

I haven't worked with LH2 since the mid-80s so I'm pretty far out of the
loop. It could make a nice big bang but otherwise is pretty hard to see
when it burns, especially in daylight. Don't know if the Apollo-era NASA
guy I used to work with was pulling my leg, but he said they would look for
leaks/fires in the ground equipment by holding a broom out in front of
them! Highly-radiating solid propellants work much better for fireworks.

Hi Paul,
Cool video, thanks.
Are you British? Could you bring the LH2 to our Fourth of July
Celebration?
That size Rocket could accommodate a large quantity of LH2 in it's nose
cone to collect Data Points on Performance of Hydrogen in Air Breathing
Rockets.

Interesting launch of the EXOS Sarge 3 at Spaceport America. Looks like
they had engine gimbaling issues but had a successful non-destructive
flight termination (this is speculation on my part based on the fact that
the rocket was venting/dumping what looked like a significant quantity of
propellant while coming down under its parafoil):
