I don't quite get why they say 'the Sun's visible output peaks in the green'. And immediately follow that up with a diagram where the peak is somewhere between blue and cyan... Or are my eyes off?
The 2nd image, to me, seems to show that green has a wider amount of emitted green light:

I hope I don't sound too argumentative, because I really don't actually care too much about the exact color of sunlight. But I think this is a diagram from earth's perspective. It has these dents in the longer wavelengths where certain frequencies get absorbed by elements it traveled through, and the UV is filtered out. Both indicators it went through the atmosphere.
Yea I don't really get it either. My physics is not particularly strong though.
What they're really saying is that the dominant wavelength our sun emits is around 500 nm. Which by definition is green light. Astronomers also call everything heavier than helium a metal, which isn't true but that's how they work.
