Book Description
This book summarizes and integrates the social scientific research on racial colorblindness, focusing primarily on work within the field of psychology. A new multi-variety colorblind framework is presented, which provides theoretical coherence to the present literature as well as a guide for future research. After considering the historical context in which colorblind ideologies have manifested and operated, research is presented that establishes how the colorblind mentality ignores important racial realities and tends to harm racial minorities across a wide variety of domains. Beneficial alternative ideologies are discussed, as are strategies that may be useful in challenging the colorblind ideology. This book will be of interest to both researchers and theorists who study racial ideology, as well as social justice advocates and practitioners who contend with racial colorblindness in real-world contexts.

Book Description
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1855 edition. Excerpt: ... in this section, and the confusion of red petals with green leaves, to which the author has referred, as proving the obscurity of red to Mr Troughton's eyes, is so nearly universal among the colour-blind, that I may. thus far adduce Sir David as at one with me in regarding red as appearing dark or darkish when seen by them. He holds, however, also, it will be seen, the remarkable opinion that the red light of the spectrum may appear much brighter, instead of much darker, to a colour-blind eye than to a normal one, in consequence of the former not perceiving the red, but instead thereof, yellow light of the same refrangibility, which makes a much stronger impression upon the retina. Additional observations can alone determine whether the anticipated phenomenon ever occurs. Its occurrence, however, would not be at variance with the appearance of red or crimson bodies as black to a colour-blind eye, as they do not transmit or reflect yellow rays to affect the retina. It is otherwise with scarlet bodies, which should appear as bright yellow to eyes which simply ignored red. But it is with green, not with yellow, that scarlet is systematically confounded by the colour-blind, as a review of all the recorded cases will fully demonstrate, and the green thus identified with scarlet is not a pale or yellowish green, but a full, and often dark, shade of that colour. Thus, Dalton compared sealing wax to one side of a laurel leaf, and a red wafer to the other, and his doctor's scarlet gown to the leaves of trees; nor was his case in this respect peculiar, for the colourblind are constantly found unable to distinguish the petals of the scarlet geranium from its leaves, the flowers of the wild poppy from the unripe corn amongst which it is growing, and...

Book Description
"Catanese's beautifully written and cogently argued book addresses one of the most persistent sociopolitical questions in contemporary culture. She suggests that it is performance and the difference it makes that complicates the terms by which we can even understand 'multicultural' and 'colorblind' concepts. A tremendously illuminating study that promises to break new ground in the fields of theatre and performance studies, African American studies, feminist theory, cultural studies, and film and television studies." ---Daphne Brooks, Princeton University "Adds immeasurably to the ways in which we can understand the contradictory aspects of racial discourse and performance as they have emerged during the last two decades. An ambitious, smart, and fascinating book." ---Jennifer DeVere Brody, Duke University Are we a multicultural nation, or a colorblind one? The Problem of the Color[blind] examines this vexed question in American culture by focusing on black performance in theater, film, and television. The practice of colorblind casting---choosing actors without regard to race---assumes a performing body that is somehow race neutral. But where, exactly, is race neutrality located---in the eyes of the spectator, in the body of the performer, in the medium of the performance? In analyzing and theorizing such questions, Brandi Wilkins Catanese explores a range of engaging and provocative subjects, including the infamous debate between playwright August Wilson and drama critic Robert Brustein, the film career of Denzel Washington, Suzan-Lori Parks's play Venus, the phenomenon of postblackness (as represented in the Studio Museum in Harlem's "Freestyle" exhibition), the performer Ice Cube's transformation from icon of gangsta rap to family movie star, and the controversial reality television series Black. White. Concluding that ideologies of transcendence are ahistorical and therefore unenforceable, Catanese advances the concept of racial transgression---a process of acknowledging rather than ignoring the racialized histories of performance---as her chapters move between readings of dramatic texts, films, popular culture, and debates in critical race theory and the culture wars.

Book Description
Originally published in 1925, this book embodies the results of research on red-green colour-blind subjects, supplemented by brief accounts of blue-yellow, total, and acquired colour-blindness to complete the description of the different forms of the defect. After a historical survey of previous work by such men as Dalton, Helmholtz, Rayleigh, Edridge-Green and others, the author deals with the most important theories of colour-blindness, and with a description of the tests and a discussion of their results.
