Purkinje effect - Wikipedia. Simulated appearance of a red geranium and foliage in normal bright-light (photopic) vision, dusk (mesopic) vision, and night (scotopic) vision The sensitivity to light in scotopic vision varies with wavelength, though the perception is essentially black-and-white. The Purkinje shift is the relation between the absorption maximum of rhodopsin, reaching a maximum at about 500 nm, and that of the opsins in the long-wavelength and medium-wavelength cones that dominate in photopic vision, about 555 nm.[3] In visual astronomy, the Purkinje shift can affect visual estimates of variable stars when using comparison stars of different colors, especially if one of the stars is red. Physiology[edit] The Purkinje effect occurs at the transition between primary use of the photopic (cone-based) and scotopic (rod-based) systems, that is, in the mesopic state: as intensity dims, the rods take over, and before color disappears completely, it shifts towards the rods' top sensitivity.[5] History[edit]

Which, in a sense, it is: both take you on a mind-boggling journey. Opting for the hard version, I am placed on a sliding medical bed, counselled some more and locked in the sphere. Then I see a cityscape of vertiginous skyscrapers, with no earth below. But the most important part of the experience is that you do not know what is inside and outside your head.

For instance, the Bassa people in Liberia only have two words for classifying colors (ziza for red/orange/yellow and hui for green/blue/purple), while the Inuit reportedly have 17 different words for white alone (which are modified by different snow conditions).
