Thanks 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!".
