protanopia

n. red–green color blindness in which the deficiency is due to the absence of the core photopigment sensitive to red light, resulting in red stimuli appearing very dim and confusion between red and green (see dichromatism). The condition may be unilateral (i.e., color vision may be normal in one eye). See also deuteranopia.

disidentification

1. a protective mechanism whereby one removes a potentially harmful characteristic or experience (e.g., one that causes stereotype threat) from one’s self-identity as insulation from anxiety or failure.

2. in meditation, a benign separation from one’s sense of self in order to gain self-knowledge. It is a stepping away from self-identity to attempt to observe oneself objectively.
