My kid asked me why the stars are different colors in photos

I was showing my 8-year-old some nebula pictures I took last month, and she pointed at the Orion Nebula and asked why it was pink and blue instead of white. I gave my usual answer about filters and processing, but she just said 'So they're not really like that?' That hit me different. I realized I'd been so focused on gear and data that I forgot the simple wonder of it. How do you explain the gap between raw data and the final image to someone new? Do you show them the black and white files first?

That "so they're not really like that" question is a gut punch. I show the raw black and white files and say it's like translating invisible light into colors we can see.

But come on, it's just space pictures. People get too deep about it.

Honestly I agree with @viola_lopez30 that people overthink this. The final color image is the real one because it shows the science. Those pink and blue hues map to real elements like hydrogen and oxygen. Showing a kid a boring black and white file just kills the magic. The wonder is in seeing the hidden structure, not in the raw data. Why make it more confusing by showing the unfinished steps?
