Acyanopsia

/ˌeɪsaɪəˈnɒpsiə/ noun

A form of color blindness where someone cannot see the color blue.

From Greek 'a-' (not) + 'cyan' (blue) + 'opsia' (vision condition). The term combines the prefix for negation with the color cyan and the medical suffix for seeing, first used in 19th-century medical terminology to classify color vision deficiencies.
