  • Neptune, long believed to be dark blue, is actually very pale like Uranus, scientists say.
  • They used modern telescopes to re-assess artificially enhanced images taken by NASA's Voyager 2 probe.
  • We can now see how both planets would likely look to the naked eye.

Neptune isn't the rich royal blue it was believed to be for decades, scientists say.
