The subject is asked to choose the dot closest to the central hue. Among the four peripheral dots, three peripheral colors are designed in such a way that, it makes confusion with the central color in protan, deutan and tritan deficiency. [5] The fourth color is an adjacent color in D-15 sequence [2] and that would be most similar to the ...
