I've often wondered about this "true color" thang.
If you could fly up to within a 10 light years or so to say M17, would you
see the red colors? I imagine not.
So true color only appears when you use a long exposure device. I see that
rendering true color is important for scientific reasons... but for me, I
really enjoy the artistic panache that imagers use to draw out the detail
and pull us away from this planet.
