If, like me, you searched the internet for clear articles and papers that gave the answer to the Sun's color, you would have found only conflicting color answers. (In the last few years I am beginning to see some improvements, but publications have a long way to go.) Since the Sun's actual "true" color will not importantly change the direction of mainstream astronomy, it seemed like a great project for an amateur astronomer. But why bother?
Friends encouraged me directly and indirectly.
Physics isn't all that hard.
There was nothing better to do.
All the above.
Yes. I had, somehow stumbled into my first internet forum, Phil Plait's Bad Astronomy Board (it's now www.bautforum.com) after merging with Fraiser Cain's Universe Today wonderful internet magazine. There are astronomers, physicists, and lots of characters like me who are active there, and they discuss hundreds of astronomy topics. For instance, Brendan Ward from Ireland, and others like him, would joke about the various escapades that we would come up with in order to discover the Sun's color. Their encouragement is what kept me going.

After I became active in that forum, which occasionally discussed the Sun's color, I recall an interested astronomer, and author, Dr. Bill Keel (U. of Alabama) explaining how he determined the Sun's color while he was at Kitt Peak observatories (near Tucson) working with stellar spectrums of stars hotter than our Sun. As Bill told me, "...I overplotted several of them [hotter stars] on a G2 V [Sun's class] stellar spectrum to see which one was the best match, the idea being that the visual appearance of that kind of star down here below the murk would be a good visual proxy for the Sun seen from space." I was a little perplexed at first at what he was saying, but it if you don't get it, don't worry. This was still an approximation, but it was a good one, and his color conclusion turned out to be correct. What color did he find? Well...

You're kidding, right? Please try again.

No, I had plenty of irons in the fire and time was a problem. I also feared this would only make me look silly. Ok, it wasn't all that much fear but I did not need to contribute additional information demonstrating my lack of knowledge.
No, please try again.
