At about midday, what color is the sun to you? [Most people say it's yellow but, truly, it looks white to me]

Answer 1

White...

Answer 2

In space, the Sun would look white, because it emits most of the wavelengths visible to the human eye. Some wavelengths are reabsorbed by gases in the Sun's atmosphere, but the missing wavelengths represent a very small and unnoticable portion of the Sun's total output.

On Earth, it's a slightly different story. The atmosphere scatters some of the blue and violet light in sunlight, shifting its color towards the red-orange-yellow end of the visible spectrum. The shift is small, though. I wouldn't fault you at all for saying the Sun looks white, because at its center, it is. The fringes of the Sun's glare have a yellowish appearance, and I think that's where most people get the idea that the entire Sun is yellow.

Answer 3

It´s green!
The sun is so bright our eyes cannot truly perceive it. And as everyones eyes are slightly different everyone will see the sun slightly different. I have looked straight into the solardisc (not recommended!) and for me it actually looked pitch black. When your eye gets so overloaded, due to the brightness of a lightsource, that the object looks black it is safe to say your retina isn´t feeling too good...
The suns blackbody intensity actually peaks within the green part of the spectrum. The effects of our atmosphere pushes the curve towards the longer wavelengths which makes it more yellow. Most people sees the sun as yellow and some see it as white. Our eyes don´t see all color equally well. The cones in our eyes pick up red, yellow and blue photons best while we don´t see blue-green photons very well at all. And then there is the matter of our brain producing colours which it does by combining the photons our cones has picked up. So we perceive colours in the yellow-green part of the spectrum best while we perceive blue and orange less well and violet and red the least. We see yellow and green about the same but due to the scattering effect of the atmosphere the dominant colour coming from the sun is yellow.

Answer 4

Yes, it looks white. We often think of the Sun as yellow because that's how it appears low in the sky, when looking at is is both less avoidable and less painful. It looks yellow then because it's filtered through more atmosphere, which scatters away the shorter wavelengths.
