The sun's light peaks in the green wavelength range, approximately 450-550 nanometers.

“the Sun's light though actually Peaks slightly in the green we don't actually notice this because our eyes are and we're used to thinking of it as very yellow um it happen and this the reason for this can be you know substantiated by U night vision glasses what color is the light coming in it's green right they amplify versions of these things why because your eye is very sensitive to Green Light it's even more sensitive to Green Light than yellow light so and that's because the sun which is what we've evolved to adapt to being most sensitive to sunlight is more greenish than yellow so there's more power at the wavelength like somewhere between like 450 and 550 nanometers”
