PURPOSE To develop and assess new color vision tests to be used in evaluating faulty color recognition. METHODS We developed new color vision tests to evaluate faulty color recognition. The two types of color vision tests, designed to assess faulty color recognition in color vision deficiencies, are based on principles that are different from those of the conventional color vision tests. In t...

Our question is, how do things look to the color-blind? But what does that mean? Who are the “color-blind”? Approximately 7 percent of males and fewer than 1 percent of females (of European descent) have some form of inherited defect of color vision and as a result are unable to discriminate some colored stimuli that most of us can tell apart. (Color defective is an alternative term that is oft...

There have been relatively few attempts to represent sight or blindness ontologically. This is unsurprising as the related phenomena of sight and blindness are surprisingly difficult to represent ontologically for a variety of reasons. This paper discusses those reasons, explores the current attempts to represent sight or blindness, and how these attempts fail at representing certain types of b...

Red-green color blindness, “Daltonism,” is the most common single locus genetic disorder, affecting 6% of men worldwide. Gene therapy is a potential means of correcting the defective or missing locus through the injection/transplantation of a normal transgene. Through the evaluation of one case study, gene therapy has cured colorblindness in squirrel monkeys, and may provide promise for humans.

Increasing trainees' multicultural counseling competence (MCC) has been a hot topic in counseling. Scholars have identified predictors (e.g., race/ethnicity, color-blindness) of MCC, and educators provide multicultural training for trainees. Using a sample of 370 psychology trainees, this study examined whether multicultural training (a) moderated racial/ethnic differences on MCC and (b) change...

In this article, we examine the pervasive endorsement of racial color blindness—the belief that racial group membership should not be taken into account, or even noticed—as a strategy for managing diversity and intergroup relations. Despite research demonstrating the automatic perception of race (and thus the seeming improbability of actual color blindness), the color-blind approach to race has...

This article takes on the cultural politics of “if they only knew” as it relates to alternative food practice. It draws on surveys and interviews of managers of two kinds of alternative food institutions—farmers’ markets and community-supported agriculture—to illustrate the color-blind mentalities and universalizing impulses of alternative food discourse. The ways in which these discourses inst...

BACKGROUND Simulcheck evaluates Colour Simulation Tools (CSTs, they transform colours to mimic those seen by colour vision deficients). Two CSTs (Variantor and Coblis) were used to know if the standard Simulcheck version (direct measurement based, DMB) can be substituted by another (RGB values based) not requiring sophisticated measurement instruments. METHOD Ten normal trichromats performed ...
