Why doesn't the Sun appear green to our eyes? The spectrum of the Sun as seen at sea level can be seen at https://commons.wikimedia.org/wiki/File:Solar_Spectrum.png so we can see that wavelengths around green to yellow are the ones that are the most present.
The human eye seems to be more sensitive to green wavelengths (around 555 nm which is plain green) compared to others: see https://en.wikipedia.org/wiki/Color_vision#/media/File:Eyesensitivity.svg.
However the Sun appears mostly white/yellowish. 
I don't understand why. The human eye sensitivity for orange/yellow/blue is lesser than for green. Much lesser in case of red wavelength. So even though the spectrum is a continum of all these wavelengths why is the eye fooled toward white?
And why more toward yellow than green?
Thanks.
 A: Note the vertical scale on the two graphs you gave: The solar spectrum at sea level is given as an intensity (power per area), and it is very nearly flat over most of the visual range. The eye sensitivity is given as a percentage, which the wikipedia page where it is used does not explain beyond calling it "normalized" and "relative brightness sensitivity." If this percentage is akin to a quantum efficiency, the probability that any one photon gets detected, there is a very natural possible explanation for this effect: If rather than a power-based intensity we use a photon number based intensity for the solar spectrum, its maximum will be at lower photon energies (redder colors) where the same power corresponds to more photons.
Perceptions are always tricky: Neither our eyes or our brains tend to function quite the way one might naively expect, in lots of ways. Hence much of the full explanation might not depend much on (photon) physics at all.

Human vision and perception of colors is a complex process. It is safe to say humans are not very good at determining the actual spectral distribution of light they see. The sunlight may very well have frequency distribution that has maximum in green and humans may still see it as having different coloration. That is because the frequency distribution characterizes square of the Fourier component of electric field of the sunlight and this need not have necessarily any simple relation to how humans perceive colors for light that is not monochromatic, like sunlight.
Human perception of color depends in a non-trivial way on the whole spectrum of the light, not just the part where the maximum is.
Well-known daily example of this is perceiving color of light emitted by the RGB pixels of a TV / computer monitor. When you look on the bright bar above, you probably see bright yellow, but in fact the Fourier component of the electric field of the light coming from this rectangle has almost negligible component at frequency corresponding to yellow monochromatic light. The perception of yellow is accomplished with combination of red, green and blue light regulated to appropriate intensities.
A: Mostly working off this wikipedia article, so information would best be further confirmed.
From the article, "The color yellow, for example, is perceived when the L cones are stimulated slightly more than the M cones...." (Further questions here probably is best asked in the Biology StackExchange) Very much as Ján Lalinský says, colour perception in humans has many non-trivial behaviors - single-wavelength response is not generalizable to broad-spectrum response.
Looking at the Normalized responsivity spectra, the L and M cones both have very broad responses, extending out over 100 nm in either direction. L cells also seem to have a broader response, which might cause them to activate stronger in even-intensity-broad-spectrum light.
Aside from that, based off the spectrum of sunlight at Earth's surface (taken at one point, but should be roughly similar everywhere), while there is a slow drop-off going from green towards red, there is a very sharp drop-off going from cyan to purple. Therefore, since M cells respond more to blue-purple than L cells do, this probably overwhelms the weaker intensity drop-off on the overall shift of L cell response range towards the red range of sunlight.
Either effect, or perhaps a combination, would produce the slightly stronger stimulation of L cones than M cones necessary to produce the sensation of Yellow light.
A: I am just rewriting what I wrote in a comment to make it more visible, since I think I found out the answer: the solar spectrum as seen on Earth's surface has much less violet and blue than both green and red according to the first link I posted. So mixing all colors should be slightly like mixing mostly green and red (and yellow/orange) than mixing blue/green/red, hence the yellowish color we see instead of greenish or white.
