Exploratorium people,

You imply in your explanation for the limitations of peripheral vision that
the rods in the retinal periphery are responsible for daytime peripheral
vision. Rods work only in dim light or at nighttime: they are not active
at all in daylight or room lights. I have contacted the people at
Webvision about the lack of color vision with peripheral vision and Helga
Kolb of that resource explained that the few cones in the periphery do not
feed into color selective channels--however, they do detect the objects in
the periphery.
