Building on the algorithmic scheme developed by the author, a new computational method is developed to determine an ergonomically optimal set of CRT colours. A set of colours is considered ergonomically optimal when two conditions are met: (a) the smallest colour difference, CIELUV ΔE, between colours is as large as possible, and (b) the selected colours obey certain luminance and saturation constraints. The proposed method is unique in that the colour set is calculated assuming a nonfixed ambient. Two sample applications illustrate the results of the extended algorithm. These results are of particular relevance for the human factors specialist who has to advise on the type of colours to implement on CRT displays that are intended for use in varying illumination conditions.
