...not known, yet. :-?

If you do happen to know, with substantiation, the true extraterrestrial color of the sun, after it's intensity has been attenuated to a normal flux for our eyes, I will be most appreciative if you share this important knowledge. I could then stop my troublesome quest.
Abstraction:
This is a very complex subject of enormous triviality, yet, possibly, warm and tender for the hearts of all mankind. “Complex” because it is a mystery why it is a mystery. The Sun's color is fairly easy to obtain - reproduce it's visible spectrum (@AM0), and you got it . (Yet, this is not as easy as I hoped it would be. :x )
I have not found much in astronomy regarding prior efforts or even a prior
a priori oratory. (I know ‘cause I have spent dozens of minutes googling.) From his book, the BA has clarified nicely the color which the sun is not - yellow. But the begging question (now a serious itch) remains - "what color is it really?".
The Sun's color is also complex in the sense one can easily say that this subject is clearly over the heads of most astronomers and physicists. This statement can not be said very often, obviously. Considering the consistency of the subject being over their heads, around noontime everyday, you would think they would consider it with greater interest. Perhaps they are.
Maybe additional complexity is inherent in the sociological/psychological aspects of this topic. Let’s say I’m an astronomer. Hmmmm, ok, let’s say you’re an astronomer. You were on the neutrino team arguing with physicists about the neutrino problem. You help show that they have mass and the single-flavored nuclear core neutrinos emissions turn into all three flavors. Thus, the massless neutrinos now have mass and the 1/3 issue is resolved. You finally have the physicists on their heels at a major luncheon. You summarize the winning arguments on the issue and you sense the sea of accolades rising before you because of your proven mastery of the Sun. Just as you have the servers place the main entre (crow) on the physicists table, one physicists stands-up in the crowd and demands - “but can you tell us the color of the Sun?”. Yeowww!
Therefore, I hope to discover this knowledge and pass it to the folks I greatly admire - astronomers. (Be clear, I admire physicsts also) Thus, saving them from the horrible and inevitable fate illustrated above. Naturally, this should be done under the table so as to not cause disgust among physicists once they have discovered their lost opportunity to cast anguish upon our noble and stellar scientists.
The following is limited information on the solar determination device as it makes light of the experiment itself. However, I can share some things. Since the solar irradiance is known both above our atmosphere (extraterrestrial) and from our surface (terrestrial), a template can be made to reproduce the sun’s visible spectrum as the eye would behold it in space. Of course, the intensity of the light must be attenuated to allow the eye to “see” the color.
Procedure 1: Gain familiarity with prism and lenses.
Equipment 1: F2 prism and large double convex lens.
Result 1: My pants caught on fire. While recombining the colors through the double convex lens, I failed to consider the sunlight which was also passing through the lens. [who knew it would handle both?]. I noticed an alarming amount of smoke coming off my blue geans. I did not need to notify OSHA of this incident as it was minor. Also, my jeans will be a little cooler come summer.
I failed in getting my nice ebay prisms calibrated. However, new calibrated prisms have arrived.
With some help from A Hundred Pardons (real name being withheld till I have his approval), I have interpolated the prism’s index of refraction for each appropriate wavelength. This will allow sunlight color dispersion to align with the template properly.
Wish me luck.
Project name suggestions welcome. Funding is private but exceeds the S.A.D. experiment.
Eroica, prepare for trepidations.
[Many delays are likely, in fact, my son is buggin me to play ping-pong]
