I've been here for 75 years and you are quite wrong. It is always orange at sunset and sunrise, but that is due to long light propagation paths through the atmosphere and normal atmospheric scattering that more strongly affects the blue end of the spectrum. During the normal course of the day, it is bright white. If it is orange at midday, that is due to particulate matter than scatters in a different spectrum than the Rayleigh scattering that produces a blue sky. The sun has always radiated in a black-body spectrum corresponding to about 5,772 degrees Kelvin of color temperature (i.e., white light, effective average). The first measurements using the results of quantum physics took place toward the end of the 19th century. By comparison, "Daylight" LED light bulbs have color temperatures of 5,000 to 6,500 K.
I don't know if you recall this, but it has generally been the case that truly tremendous explosive volcanic eruptions, which inject huge amounts of ash into the upper atmosphere, can result in very colorful sunsets all over the world, for considerable periods of time.
Normal atmosphere scatters all color wavelengths, but more so at the blue end of the spectrum. All gaseous molecules scatter by the Rayleigh process, which gives the same result (some exceptions are the halogens, which can be visible by distinctive colors).
During the normal course of the day, it is bright white.
Yeah. It used to NOT be, is my point. In the 70s, the sun appeared to be warm yellow all day, not just at dawn and sunset. My observation is that the light from the sun has been harsh white for the last 10 years. Entirely unlike the first 40 years of my life.

You're talking about extraterrestrial radiance. Atmospheric gases selectively absorb and scatter this light, turning it into terrestrial irradiance, whichbis what Im talking about. The light we see from.our sun AFTER it passes through our atmospere and us scattered in various ways.
You've never seen the extraterrestrial radiance of the sun. You've always seen it filtered through our atmosphere, just like most humans.
I'm talking about the way it appeared to me and everyone else in the 50s and onward. The radiance from the sun is only very slightly diminished by atmospheric scattering at midday. It looks the same at high altitude, where over half the atmosphere is beneath us.
Where do you live? What is the tendency for the local weather to carry windborne dust?
You attempted to "debunk" the info by telling us about the extraterrestrial radiance of the sun and how it hasn't changed, knowing full well that the atmosphere and the gases and particulates within it change that radiation profile constantly, changing the way we see light from the sun.

No, you attempted a stawman argument which failed miserably.
I'm afraid you are trying to pick an argument, but you have nothing to say. I was referring to the actual sunlight shining from the daytime sky, not "extraterrestrial" sunlight. If you are going to trap me, please quote me correctly. And I have pointed out that the color of the sun depends on the path length of the sunlight through the atmosphere (sunrise and sunset), so you are omitting my explanation of that effect. Sorry that you don't like what I have explained, but I am under sentence of expulsion if I argue, so I will not argue. Please have a good day.
