Uranus imaged with a color camera, and with very light processing, shows its natural color: a pale blue, due to the absorption of methane in the red/infrared part of the spectrum.

Although it is very unlikely to highlight the bright polar cap (as happens with the most common post-processing colorized IR images), images like this give a fairly faithful idea of ​​how the planet looks through the eyepiece of medium/large sized telescopes in good seeing conditions.

Image not oriented.
