Had a look at NGC7662 Blue Snowball over the last few nights. It's the only object that I have ever observed that really had any color. Never seen anybody post anything about it! Anything else that has some color?

What size scope are you using? The bigger the better of course.
IC 418, a PN in Lepus, always seems to impress people. In large scopes (20+) you get some definate red color. In my 25" its quite readily apparent! Theres no doubt that you're seeing color!

I've never seen it in a 10". I can't be certain about color. All I can suggest is give it a shot. Its not up at this time of year just yet but it will be before too long

You mean IC418 is not up yet? I believe it rises at 03:01 am central standard time,to late for me! NGC7662 Blue Snowball rises at 17:02 central!

Locoman,
Try the "Blue Raquetball" NGC 6572 in Ophiucus. Small but bright planetary nebula with intense color.
The past week I also saw color in the Saturn Nebula NGC 7009 and also in NGC 7027 in Cygnus. (both green, both Planetary nebulae).
The Orion Nebula, M42, in the winter is famous for its green glow. Most nights I have trouble seeing green in the Orion Nebula, so I definitely don't have above average color sensitivity.
Good question, and reminds me to take a look at 6572 and 7662 again.
Mike

The Cats Eye, NGC6543, is another that shows color fairly well.

Per my notes, NGC 3242 (planetary) in Hydra has a blue tint; aka the Ghost of Jupiter. Viewed w/10" SCT.

Saw the blue snowball last night for the first time. Nice - not as blue as I hoped but then again the moon was almost full. The DGM NPB nebula filter helped w/ contrast only slightly. I'll have to go back and check this at a later date.

Doug,
I've seen the Blue Snowball from here in the red zone with my 10" Newt. It has a bluish tinge. Also, the Saturn Nebula has a bluish color. I've seen tinges of red and yellow in the Ring and Dumbbell Nebulae through my 10" in a yellow zone site. Emission nebulae tend to be greenish, for instance M42 and M8, the Lagoon. Reflection nebulae share the color of the stars that shine on them. Stars themselves are, in fact, Deep Sky Objects, and they can be white, bluish, violet, orange, yellow, red. Some are a very deep, pretty red, such as the Garnet Star in Cepheus. No stars are actually green, but some doubles look green next to their partner. Of course, Uranus is greenish and Neptune has a bluish hue, but this is the DSO forum, so I guess they don't count. 
Clear Skies,
Mike

Hmm... Is Saturn Nebula greenish or bluish? I'll have to look at my notes. Maybe green-blue or blue-green? I don't recall it being a definite green color.

I've read where older people tend to see green in planetary nebulae, where younger ones see more blue. I'm 55 and see green in the Saturn nebula. I haven't seen the blue snowball in a while so can't say.

Well, I'm 53 and I still see plenty blue in the Blue Snowball. Maybe my memory's not so good, though, because I can't recall now the exact color of the Saturn nebula. I saw it a couple months ago at a dark site. I'd say that it was blue-green.

I wish I could look through someone elses eyes. I feel I have excellent colour vision during daylight. I am posting this while standing in our shop surrounded by colourful candy packets, magazines and luridly coloured Coke and other soda bottles and point of sale advertising. The whole place is awash with bright colours. I feel like I am percieving them with all the intensity they have to give.
Observing at night???
Black and White only I am afraid. Sure I can see that Alberio is a differetnt colour pair and Aldebaran and Betelgeuse have an amber tint but thats the extent of my astro colour perception.
I can't help but feel that much like those who claim to see the central star of m57 in their 10inch are using averted imagination, that those who describe colours with the 'ish' tagged onto the end of the colour decription are using a bit of imagination too.

Spent some time with the BS at the Oregon Star party, very, very blue at about 250X in my 8". Just gray Saturday night with my 5" at home.

So what I saw was my imagination? If so then I will try to use my imagination a lot more when I observe,that way I can see more than I thought! My wife had a look and she saw Blue in it to. My 21 yr old daughter said it looked blue. Imagination runs wild in my family!

It is kind of a bluish-green coloration that is difficult to describe, as it is almost on the border between blue and green. At times, it is *almost* an emerald green, but other times, it has a more bluish cast. Here is a drawing I did of the Saturn Nebula (NGC 7009) which I have tried to duplicate the color.

In my early 61 year old eyes, the Saturn Nebula has a pale light green colour.
