I apologize for my bad English, higher frequency is shorter wavelength
About the colors and efficiency: It's not all quantum efficiency you are looking for, it's also many other processes that are driven by the different wavelengths. Green light actually is more efficient in high intensity white light than blue and red. There are also many more pigments than just chlorophyll.
The PAR curve (well, it's not the PAR curve but the McCree curve) was defined in the 70's of last century and defined for light levels of about 100 umol. Since then a lot more research has been done and at high intensity the efficiency of the different colors is much closer than the original McCree curve.
So, translating the McCree curve in a graphic in "plant requirements" is a bit let's say inaccurate.
