Mesopic vision is a combination of photopic vision and scotopic vision in low but not quite dark lighting situations.[1]
The combination of the higher total sensitivity of the rods in the eye for the blue range with the color perception through the cones results in a very strong appearance of blue-ish colors (eg. flowers) around dawn.
The human eye uses pure scotopic vision in the range below 0.034 cd/m2, and pure photopic vision in the range above 3.4 cd/m2.[2]
