What Color is the Sun?

What color is the Sun when looked at from Earth and from outer space? Everybody knows that the Sun is a very hot star. It gives out light and electromagnetic waves. These waves have colours ranging from violet to red. The colour yellow is what most people associate the Sun with. But is that the true colour of the Sun? Does the Earth’s atmosphere have any effects on its colour? If one would go to space, would the Sun still look yellow?

One should first know the spectral of the Sun’s light. If the red, blue and yellow in the spectrum of the Sun are of the same amount then the colour that it should bring forth is white. The Sun is so strong, bright and hot that it emits these wavelengths. Thus it gives the appearance of being white. But it also has very strong lines of yellow that is why it looks yellowish.

What color is the Sun from Earth? If one is looking at the Sun from Earth then the Sun would look more yellow than when viewed from space. The atmosphere of our planet actually has something to do with this. The blue light actually scatters once it reaches the atmosphere thus, making the colour yellow more prominent. The sky, which is blue, has this contrasting effect on the Sun’s yellow colour and enhances it more.

What color is the Sun from space? It is whiter in colour with a slight tint of yellow. Compared to the Sun being observed from Earth, it would look more whitish and bright. That is because there is no atmosphere to disseminate the blue and the background from space is black. There is no contrast to make it look more yellow.

The Sun has many colours and because of the intensity of those colours our eyes can’t take them all on that is why it appears white. But because it has strong lines of yellow it gives that slight yellowish tint. So it is safe to say that the Sun is white with a yellowish tint.

    The eyes of color-perceiving animals, including the human, have automatic white-balance that is, all colors we’ve seen during the last half hour or so are averaged and the result is called “white” by our eyes.

    So, at normal daylight, the sun is actually white (outside our atmosphere), but depending on “background” (blue sky, white to gray clouds) and atmospheric scattering, it looks something from yellow over orange to red to us.

    Colors are an essentially relative measure, as far as our eyes are concerned.

    If we define colors by wavelengths, the wavelength with maximal emission is indeed about 500 nm, which is green, but if we look at the energy of the photons, the maximum is at a somewhat different position. But if we want to convert the sun’s spectrum into a color, we had to integrate it weighed with the sensitivity of our retinas at that wavelength/frequency, which might give a result different from the first two.

    Cat is the closest. The color of the sun can be found simply by looking at it’s solar radiation graph. Our sun’s main product is light at wavelength 525 nm. This is green.

    The sun has the colour of a Rainbow.And that is what the sun is emiting as light

    The sun is actually turquoise, according my astronomy professor.

    wow

    I believe the colours of light that contribute to the colour white are red, blue and green, not yellow as in light the primary colour is green not yellow. I may be wrong but it may be something you want to double check. Other than that the whole website is brilliant and very informative.

    The Sun is a nearest star it is large its the biggest thing on the world the sun.
    The sun is bright so much its so awesome :D
    If you look at the sun in the telescope your get blind but you wont fell It .
    How come people know this stuff ?

    hey this is my homework omg i got lots of things to say yes yes !

    Sun appears red / yellow when viewed from Earth because these are the wavelengths of light being reflected in the atmosphere. This is also why the atmosphere appears blue, the blue wavelengths from the indirect light from the sun are being reflected giving the appearance of a blue sky. In space the sun looks white as all the colors of light are being mixed together, and when this happens we see white light.

    i don’t no

  • mmm

    Dont need to read this WHOLE page,
    Just read this.
    Its red.
    End of discussion.

    As per the present theory, Sun light has the seven colours or variable frequency and wave length containing electromagnetic waves. But, my point of view this is not true. Sun is emitting only one electromagnetic wave, that is ultraviolet rays. This uv rays mingled with the planets saturn, moon, venus, mercury, jupiter,mars and sun gravitation force. Then UV rays changed into seven electromagnetic waves as a vibgyor. Other planets in our sun family too far from earth. So neptiune, uranus and pluto planet’s garavitation or attractive force not reach until earth. This concept , I derived from indian astrology. If we will study indian astrology deeply, we can understand everything.

    I can’t find any good pic’s of the sun in space. It would be cool to see a high-res picture from the ISS of the sun. Any sites you would recommend? =]
