Hi:

 

I have two favorite wavelengths [colors] of visible light. These two wavelengths of light [when emitted monochromatically and perhaps together as well]:

 

1. Cause the least amount of stimulation [hopefully none] of the rods of the average human retina

2. Cause the least amount of stimulation [hopefully none] of the blue cones of the average human retina

 

Wavelength-1 is reddish-green while wavelength-2 is greenish-red.

 

Both wavelengths [even if view separately] will stimulate both red and green retinal cones, hence the terms “reddish green” and “greenish red”. However, reddish-green causes more stimulation of green cones than red cones, while greenish-red causes more stimulation of red cones than green cones.

 

Therefore, when viewing wavelength #1, the average human will likely express perception of green. However, when viewing wavelength #2, the average human will likely express perception of red.

 

What wavelength of light most closely fits wavelength #1?

 

What wavelength of light most closely firs wavelength #2?

 

 

Thanks,

Take your pick:

 

 

Looks like anything longer than 600nm has negligible blue and rod response.
