technically it's white, right? seeing how sunlight, when broken into a prism, contains all the colors of the spectrum....
all the colors of the spectrum together=white
yeah, white is my answer.....
Even with the rainbow explained, the puzzle of color still baffled scientists. The riddle was solved around 1860 by James Clerk Maxwell (pictured on the left), the brilliant Scottish physicist who also gave us the basic equations of electricity, the ones that predicted electromagnetic waves (see Section S-5). Maxwell showed, while still a student, that two kinds of color existed, depending on whether it was perceived by an instrument or by the human eye:
An instrument using prisms ("spectrograph") will reveal that the human eye can be fooled: different combinations of rainbow colors may look the same to the eye.
- "Spectral color," i.e. the colors of the rainbow and their combinations. The amount which each part of the rainbow spectrum contributes to a beam of light can be determined by splitting the beam with a prism.
- "Perceived color" reported by the human eye to the brain.
Our eye contains three kinds of light-sensitive cells, each sensing a different band of colors--one band centered in the red, one in the green and one in the blue. Any color which we see--including brown, olive-green and others absent in the rainbow--is an impression our brain conveys as it combines signals from these 3 color bands. Color-blind persons lack some types of eye cells, and their world lacks certain colors, or even (for those having only one kind of cell) any color at all. Color blindness is much more prevalent in men; in women, on the other hand, a rare mutation exists whose eyes have four different kinds of receptor cells. The rest of us can only guess what colors those ladies must be able to see!

anyway the sun is white
Since the Sun is alone in space no other light source will trick us in seeing anything other than a white star. Yet there is more evidence for a white Sun.The Sun is a ball of gas and the layer that we see is the photosphere. As we look into the central portion of the Sun's disk we are able to see deeper into its atmosphere. As we peer into deeper regions of the Sun, we are seeing hotter and hotter gases. The Sun's surface temperature is about 6,390K in the central zone. As we look to the limb of the Sun, we see only the very top of the photosphere where the Sun is only 5,000K.
This temperature gradient is part of what is known as the center-to-limb variation (CLV). It is important to us because if the Kitt Peak image is not yellow at the limb, at 5000K, then there is really no hope, once again, of the Sun ever appearing yellow. [In 4 or 5 billion years, that will be a different story.]

**EDIT:
The Sun has a spectral class of G2V. G2 means that it has a surface temperature of approximately 5,780 K (5,500 C) giving it a white color that often, because of atmospheric scattering, appears yellow when seen from the surface of the Earth. This is a subtractive effect, as the preferential scattering of shorter wavelength light removes enough violet and blue light, leaving a range of frequencies that is perceived by the human eye as yellow. It is this scattering of light at the blue end of the spectrum that gives the surrounding sky its color. When the Sun is low in the sky, even more light is scattered so that the Sun appears orange or even red
