It is as yellow as my avatar above, which is an unfiltered image from Kitt Peak's McMath Solar telescope. The yellow Sun color conundrum comes from, I strongly suspect, spectral colors releative to Vega beginning in the 1800s. The Sun is more yellow shifted compared to the hotter and "white" Procyon, "blue" Vega and "violet" Rigel. [Colors from Flammarion's Book "Astronomy", 1880.]

Another approach is to take the SED and convert it to a photon flux distribution to be more consistent with what the eye observes.
Here is one for the Sun, as seen from space.
It seems reasonable that the Sun would be white given such an even distribution. [It is a little weird for me that there is a yellow peak (or pimple).] Perhaps this is close to an ultimate white for the average eye, not that any one SED is likely defineable as such.
Another interesting thing for blue stars is the relative increase in all the other colors whenever you increase star temperature. Blue will increase faster than the red end of the spectrum, but you have to reach temperatures of around 15 million kelvins to get a SED approximating a saturated blue sky. Bluish white will best represent the O and hotter B stars.
