I’m more a photographer than an astronomer but as far as I understand it those false coloured images are produced by monochrome sensors that are sensitive to a broad range of frequencies which have filters placed in front of the sensor to seperate out a specific frequency and then to create a single image they will photograph with different filters to get various “colours” then that data is mapped to the colour your monitor can display.
Whether the colour is true to life is a really complicated question for basically any photo you see lol. like, there is no simple objective answer for any photo imho unless it’s obviously a no
- oersted 2y agoThanks for the context. I'm not too experienced in this area, but I am aware of the very relative nature of color in imaging, that's why I quoted "what it actually looks like". I guess what I'm asking is if it looks so colorful when you look at it with your eyes from low orbit. Generally if those different regions are clearly visible, however lifelike the coloring is. Or is it actually just mostly flat grey like the traditional depictions. They often augment the contrast/saturation so geological features are more distinguishable or for aesthetic reasons. There's a trend of "Look! Astronomical object X is not as boring and homogeneous as you thought!".

To be honest, I don’t know A lot of the colour in these images just blurs together at the scale we see the moon at from earth, at least with my eyes, and that would still be true in low earth orbit.
