a unique form of color-blindness in which individuals have the usual three retina cones, but one of them has a color sensitivity that is different from what might be expected. In general, this causes difficulties distinguishing red-green hues. It may also manifest whereby individuals are less able to distinguish red and green the more intense the colors become, meaning that duller shades are more readily identified than brilliant shades. Also known as anomalopia and anomalous trichromasy.

ANOMALOUS TRICHROMATISM: "The individual diagnosed with anomalous trichromatism experienced extreme difficulty differentiating bright shades of red and green due to defects in conal color sensitivities. "
