Read your own post....

"Since you see the blue light from everywhere overhead, the sky LOOKS blue. "


So if something LOOKS like a duck, and quacks like a duck, it isn't a duck??? :confused:

To prove the point that because something looks a certain color doesn't mean it is that color.


So what color IS the sun?

Actually, being a Main Sequence, class G II star, the sun is indeed yellow.



sonofabitch --you're RIGHT!

Hehe, doubtful, but you'll find out later today I'm sure ;)

It's white.

White isn't a color, but it contains all colors.

Is a red herring really red, or does it just look that way?

The sun is technically sort of a very light peach/pink.

No, it's pure white. The purest of white.

Its a yellow star.....http://www.peripatus.gen.nz/Astronomy/SteCla.html
  1. O stars are massive, very luminous and blue-white, indicating extremely high temperatures (~20,000 K and up). Type O spectra show lines of ionised helium, nitrogen and oxygen. Good examples are Zeta Puppis (Naos) and Iota Orionis A – the star at the ‘tip’ of Orion’s sword.
  2. B stars are also massive, luminous, blue-white and hot (up to ~ 20,000 K). Their spectra display strong helium lines. Examples are Beta Orionis (Rigel), Beta Centauri and Beta Crucis.
  3. A stars are luminous, white, with temperatures around 10,000 K. Helium lines are absent from type A spectra, but hydrogen is strongest in this type. Alpha Canis Majoris (Sirius) and Alpha Lyrae (Vega) are examples.
  4. F stars are yellow-white, indicating temperatures around 7,000 K. Their spectra exhibit weaker hydrogen and strong calcium. Two well-known examples are Alpha Carinae (Canopus) and Alpha Canis Minoris (Procyon).
  5. G stars, of which the sun is one, are yellow with temperatures around 5,000 to 6,000 K. Hydrogen lines are weaker again; many metals are present. In addition to the sun, another example is Alpha Centauri A.
  6. K stars are orange, around 4,000 to 4,700 K, and display faint hydrogen lines, strong metallic lines, and some hydrocarbon molecular bands in their spectra. Examples are Alpha Boötis (Arcturus) and Alpha Tauri (Aldebaran).
  7. M stars include the red dwarfs and red giants. They are only very weakly luminous, red, with temperatures around 2,500 to 3,000 K. Their spectra are characterised by many strong metallic lines and also wide titanium oxide bands. Alpha Scorpii (Antares) and Alpha Orionis (Betelgeuse) are the only two first-magnitude examples.

I keep trying to believe that Kevn doesn't exist but people keep disagreeing with me and quoting him. :rolleyes:



Actually KEVN is an experiment in artificial intlligence.

What color is the Sun?
The simple answer to this question is that the Sun is yellow. Go outside and see for yourself. (But don't hurt your eyes by looking for a long time.)
For our purpose of determining the temperature of the surface of the Sun, a more precise answer is that the intensity versus wavelength curve for sunlight peaks near 500 nm.

But the question "What color is the Sun?" raises an interesting issue that is more closely related to biology and psychology than to physics. Physically, sunlight is a mixture of photons of different wavelengths. This particular mixture is very close to the color we call white. This is particularly true if we put back the predominantly blue light that is scattered out of a sunbeam as it comes from the Sun and passes through the Earth's atmosphere before it reaches our eyes. Why do we call this color white? Presumably, it is because after many hundreds of millions of years of evolution, our eyes and brains are adapted to viewing things that are illuminated with this particular mixture of photons. Then when humans started giving names to colors, they chose a special name for the special mixture that their eyes and brains were adapted to seeing.

I love the evolution part :)

So if all fish don't swim, what to the rest do? :confused:
