I notice the kit box and catalog pages show the Challenger I with orange nose cone and fin can, and two clones painted accordingly in this thread. But when you show your original Challenger I kit in the video at ~10:50, all the molded plastic parts are yellow. There's another thread where the original Challenger II cone is shown to be a different yellow, more like school bus but not quite school bus.
I also noticed that Elegoo has a yellow ABS-like resin and the color in the photos of printed parts looks pretty close to what you'd want to match the original Challengers, maybe partway in between them.

Wondering what thoughts would be about just using that material and running it raw, unpainted.
