Definitely blue-green in my 11 inch.

Welcome Mr. or Ms. Newbie. Where do you view from?

I mostly see shades of grey in Uranus and sometimes a lean in toward blue with Neptune. That obvious disk appearance is always my validation that I have an ice ball and not a dim star.

         Yep, that pic definitely looks like blue tinged slightly with green. And is a pretty good match for what I saw with my first sighting of Uranus. 

 

   Clear Skies,

      Matt.

Here y'go... imaged at about f/20 through my 10" last month... it's blue-green.

I grabbed one of the planet last night as well,  strangely, It looks Exactly like your image shared here!!

[chrysalis]

I'd also say that beyond the color, seeing that tiny disk and realizing how far away Uranus and Neptune are to be that small is mind-expanding. 

[kjkrum]

For some reason I've only ever looked at Uranus and Neptune in a 70mm f/10 refractor. I could see no color at all in Neptune, and Uranus was so faintly blue that I might have just been seeing what I expected.

Visually, I think it's mostly grey with a hint of aqua-teal. Photographically, it's more colorful [blue-green-aqua-teal].

Uranus appears approximately the same cyan color as I see in high surface brightness planetary nebulae.  William Herschel seems to have had the same impression, hence the term "planetary nebula."

I can see Uranus in my 10X50 binocular and low power telescope is white like star. Higher power at least 200 power that I can see Uranus is light green/blue and more noticeable is bigger than stars.

Nice photos of Uranus, Ryan. I actually prefer the unprocessed one to the processed.

[E_Look]

Hey, payner, I'll second that, though you're right, both are nice images.

It's been a long while since I hunted it down; however, the first time I did, it was through an F/11 80mm Celestron Firstscope achromat, with a 15mm Panoptic in the focuser, a few years shy of 30 years ago.  Will never forget how nicely Uranus stood out in the field of view possessing the color of a soft green traffic light.

That's pretty accurate 

I can't see the moons visually though [most likely due to aperture].. but the color is spot on.

        That looks like a long distance Voyager II picture, David. Nice Work! Especially catching those three moons as well. It even has the blandness effect of that time. Which wasn't fair to Uranus, that was one of its poles in Winter! There is more weather in its equatorial regions. But I have no idea what color those clouds would be, on Neptune, the clouds range through white through deeper shades of blue ( based again on Voyager II data/pics. What else?).

Nope, Hershel thought it was a comet and announced that. Only the orbit calculation from the Royal mathematicians revealed it was a planet. Uranus is not connected with the term Planetary Nebulae, a term that Hershel invented for... planetary nebulae.



By the way, I see it Blue/Azure with my C8 and a BCO ortho eyepiece.
 
Eyepieces have a great impact on colors.

               Because some of the Planetary Nebulae reminded him of Uranus! LOL

Ah I see! Thanks for the clarification - I misread the original post I quoted... How can i donwvote my onw post? LOL

[Sheol]

                     It might let you edit the reply a bit. Perhaps. 

                     With the 'Scopes William & later, John, used, the color of both Uranus & PNs would probably be very obviously green, greenish-blue, or blue. Anyway, my 8 inch definitely showed a bluish tinge, I remember it vividly, because I wasn't actually expecting THAT much color in either of the Ice Giants. As far out from Sol as they are, is it any wonder they are blue? Sooo Cold!! ( This was a joke, I know why they have those colors. )

 

                    Clear Skies,

                        Matt.

Finally found an image of Neptune (lower right) I took on iPhone through my 12" telescope. Color is  pretty much spot on versus visual.

                    Another really nice catch! Neptune is the only MAJOR planet I have left to see, btw.  Seems definitely bluer than Uranus..

A couple of nights ago I saw Uranus in my 15X binos.  Confirmed with Stellarium.  It looked like a star, next to a dimmer star.  I thought Uranus had more white than the dimmer star.  Absolutely no color.

If Uranus' altitude is low you might see effects of atmospheric dispersion.  I think celadon is a good description of Uranus' color because the color name comes from a old Korean pottery glaze which fires into the hues described in this thread.  Usually as a color name it refers to a pale blue-green.   Some celadon pottery in the museums is almost white, some more green than blue.    Is all astronomy local?  If I still lived in the American southwest I might chime in with turquoise as a description of Uranus' color.

Interesting range of colors of pottery that also includes the color of Neptune!
