Not gonna lie, using a different wavelength feels like cheating when it comes to obtaining a color.

Yeah... You can basically say "this is x-ray but represented in "

Surprisingly many seem to be in real color: white, pink, red, orange, maybe brown, probably green, and yellow. (The well-known Neptune image is false color; Hubble deep-field is IR but that is redshifted so IDK, may be "real" color too.) Too bad white, pink and red are Earth's atmospheric phenomena, of which only the aurora is really space-related, and green is just a satellite photo. Still, within NASA's scope I guess.

I thought the tops of sprites reached space

Sure but they are atmospheric phenomena because they need gas to happen.

But isn't that what colors literally/fundamentally are?

Selecting one wavelength are discarding all the others, and sometimes shifting that wavelength to a more convenient hue is great for science, but feels like cheating when looking for a specific colour.

It's like looking for pictures of red cars, and getting a car that's 90% rust, a picture taken in a forest fire, and a picture taken through red-tinted glass.
