Two color-separation positive transparencies of a scene, one projected with "red" light and the other with tungsten lamp light, were superimposed on a screen. The light was polarized so that an observer wearing an appropriate viewer could either see both images in each eye or the "red" image in one eye and the "white" image in the other. These two situations gave different results, not the same results, as some previous investigators have claimed. Land's major results cannot be "obtained… Expand

In this report a scene consisting of fourteen colored fields was viewed while one band of wave-lengths enters one eye and a different band enters the other or while both bands enter both eyes under otherwise identical conditions and it is found that color constancy is maintained under dichoptic conditions.

The hue, saturation, and brightness of a field of white light were varied by the simultaneous chromatic stimulation of neighboring retinal areas to explain the explanation of chromatic contrast based upon selective lateral adaptation and the concept of opponent-response induction. Expand
Red/white projections and rod/long-wave cone color: an annotated bibliography
This work describes Land's original red and white projections using equipment now at the Rowland Institute and shows that color from rods and L cones under the right stimulus conditions was nearly identical to cone-cone color. Expand
Red / White Projections and Rod-Lcone Color : An Annotated Bibliography
In the mid 1950’s Edwin Land, while developing instant color film, repeated James Clerk Maxwell’s 1861 three-color projection experiments. By accident, a two-color red and white projection appearedExpand
Dichoptically Viewed Colour Aftereffects Produced by Monocular Adaptation
Results obtained permitted us to assert that both kinds of colour aftereffect could be produced with white patterns on dark backgrounds as well as with black patterns on white backgrounds and did not require binocular fusion of the white backgrounds. Expand
Retinal Mechanisms of Colour Vision
This chapter will deal with those retinal responses for which wavelength of light is the important aspect of a stimulus, and the role played by various retinal mechanisms in determining the messages which pass along the optic nerve and allow an organism to distinguish colours. Expand
Evidence That the Colored Shadow Effect is Retinal
Polarized lenses were employed to present the images of the colored shadows effect separately to each eye, leading to the conclusion that the effect is entirely retinal in origin and does not involve the central nervous system. Expand
Evidence That Line Illusions Originate in the Central Nervous System
Polarized lenses were employed to present the components of four line illusions separately to each eye, leading to the conclusion that the effect originates in the central nervous system and does not require the retina. Expand
Color preferences and color usage of lower-class Negro three-and-four-year-old children
The purpose of this investigation was to study color preferences and color usage of lower-class Negro threeand four-yearold children. The null hypotheses to be tested were: (a) threeand four-year-oldExpand
Colored Backgrounds Affect the Attractiveness of Fresh Produce, but Not it’s Perceived Color
The color of the background on which products are presented may affect their perceived attractiveness. We presented five different vegetables (tomato, carrot, yellow bell pepper, cucumber, eggplant)Expand


Interspecific Transformation of Neisseria by Culture Slime Containing Deoxyribonucleate
Genetic change of Neisseria meningitidis is elicited by deoxyribonucleate preparations obtained from N. sicca by conventional methods and by crude de oxygenribon nucleate-containing slime which accumulates without experimental intervention in some cultures incubated for a period as short as 44 hours.

Color names can be used in two senses-to describe a sensation or to describe a correlate of bands of wavelengths
    When these experiments are performed with -"red" light and "green" light, and with other light combinations, the results seem to be
