From NASA an interesting attempt at “True Colors”, considering how much of the impressive astro photography is technical images with “fake” colors.
The strangest moon in the Solar System is bright yellow. The featured picture, an attempt to show how Io would appear in the “true colors” perceptible to the average human eye, was taken in 1999 July by the Galileo spacecraft that orbited Jupiter from 1995 to 2003
I’ve extended the black backdrop, the super tight crop in the original (click the link & compare for yourself) seems, again, very technical.
