Occupational colour vision needs with emphasis on aviation

Barbur, J. L. & Rodriguez-Carmona, M. (2016). Occupational colour vision needs with emphasis on aviation. AIC2016 Interim Meeting, Color in Urban Life: Images, Objects and Spaces; Book of Abstracts, pp. 431-434.


The novel experiments and tests developed for this study yield new data that describe how combinations of luminance contrast and Red / Green (RG) and Yellow / Blue (YB) colour signals affect task completion times (TCT) and the overall accuracy the operator can achieve. With appropriate design and choice of colours, it is possible for deutan applicants with thresholds < 4 standard normal CAD units to perform as well as normal trichromats when suprathreshold colours with RG and YB components are employed in visual displays. As many as 22% of deuteranomalous subjects can be included in this category. In spite of their congenital colour deficiency, such applicants can operate safely in the Air Traffic Control (ATC) environment as well as in many other occupations that involve the use of large-field, visual displays.
